The server is up and running, so the server is not an issue. I therefore suspect there must be a DNS problem somewhere.
The common denominator among those that are having the problem is that they are using connections with high latency (e.g. Satellite). Could high latency be the problem? If yes, is there anything I can do so my users will stop having this problem?
My server very slow and the is very loaded. How can I fix this problem? My server specialities and loaded softwares which are below. And sometimes there is "mysql connect failed", "Lost connection to MySQL server during query" errors. Thanks for kinds...

-- MYSQL PERFORMANCE TUNING PRIMER --
- By: Matthew Montgomery -
MySQL Version 5.0.41-log i686
Uptime = 3 days 4 hrs 34 min 17 sec
Avg. qps = 92
Total Questions = 25406284
Threads Connected = 1
Server has been running for over 48hrs.
It should be safe to follow these recommendations
To find out more information on how each of these
runtime variables effects performance visit:
.............
SLOW QUERIES
Current long_query_time = 5 sec.
You have 115 out of 25406302 that take longer than 5 sec. to complete
The slow query log is enabled.
Your long_query_time seems to be fine
WORKER THREADS
Current thread_cache_size = 8
Current threads_cached = 7
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine
MAX CONNECTIONS
Current max_connections = 500
Current threads_connected = 2
Historic max_used_connections = 110
The number of used connections is 22% of the configured maximum.
Your max_connections variable seems to be fine.
MEMORY USAGE
Max Memory Ever Allocated : 835 M
Configured Max Per-thread Buffers : 3 G
Configured Max Global Buffers : 46 M
Configured Max Memory Limit : 3 G
Total System Memory : 3.96 G
Max memory limit exceeds 85% of total system memory
KEY BUFFER
Current MyISAM index space = 35 M
Current key_buffer_size = 32 M
Key cache miss rate is 1 : 73658
Key buffer fill ratio = 34.00 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere
QUERY CACHE
Query cache is enabled
Current query_cache_size = 4 M
Current query_cache_used = 1 M
Current query_cach_limit = 1 M
Current Query cache fill ratio = 29.83 %
MySQL won't cache query results that are larger than query_cache_limit in size
SORT OPERATIONS
Current sort_buffer_size = 2 M
Current record/read_rnd_buffer_size = 1 M
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 1.00 M
You have had 14127 queries where a join could not use an index properly
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.
If you are unable to optimize your queries you may want to increase your
join_buffer_size to accommodate larger joins in one pass.
Note! This script will still suggest raising the join_buffer_size when
ANY joins not using indexes are found.
OPEN FILES LIMIT
Current open_files_limit = 2500 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
Your open_files_limit value seems to be fine
TABLE CACHE
Current table_cache value = 256 tables
You have a total of 636 tables
You have 256 open tables.
Current table_cache hit rate is 1% , while 100% of your table cache is in use
You should probably increase your table_cache
TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 2271787 temp tables, 3% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Created disk tmp tables ratio seems fine
TABLE SCANS
Current read_buffer_size = 1 M
Current table scan ratio = 28 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio =1 : 112
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform
frequent updates consider setting 'low_priority_updates=1'
If you have a high concurrentcy of inserts on Dynamic row-length tables
consider setting 'concurrent_insert=2'.

I have a lot of international users connecting to my server. They are from all around the world including the philipines , germany, etc. Im thinking those users experience distance lag (Latency?). How do i cut down on this distance lag. Should i upgrade from 10mpbs to 100mpbs would that do any good?
View 9 Replies View RelatedId like to know if I could use a remote desktop ( remotely ) as I have about 350msec latency to the server where I am planning to install it. I am planning to use remotely anywhere server .
View 6 Replies View RelatedOne of my apps is based on querying Youtube API. My response times are badly slow: something like 2 to 3 seconds. The guys on YouTube APIs Developer Forum suggested that the response time should be more like <.5 seconds.
Would you guys do me a favor and post your results for this command:
curl -w "
Total: %{time_total}
" -o /dev/null http://gdata.youtube.com/feeds/api/videos?vq=dog
It basically queries the API and tells you how much time it took API to return the data.
Please post your result and the NOC/hosting company you use. I am now considering moving to another hoster.
two setup issues:
1) We have 3 web servers each with IIS and ColdFusion. When updating the site which setup is better:
a) upload the changed file to all 3 web servers, keeping them in sync
b) move the source files to our storage server, then change the site root on the web servers to point to a network share in the storage server
Main issue: Will the network latency of fetching the source files be a performance problem?
2) We have a storage server that will serve up some audio/video via http. Which setup is better:
a) expose it to the Internet and serve it directly to the users via its own IIS
b) create a network share and let the 3 web servers serve the files
If you think long and hard about this issue you'll realize there are many cons and pros to each approach. I can't seem to make up my mind.
What would be the best provider for reaching Japan with low latency from NYC?
View 3 Replies View Relatedto buy a good dedicated server to serve my clients here. So im looking from advices on a good hosting company USA based.
But i have been ping several major hosting USA company (like, mediatemple, theplanet, etc...) and i still didn´t get a Ping under 130ms.
If i ping a good EU company i get 60 to 90ms.
I know that the distance is bigger but,
Does anyone knows any good USA hosting company with a Ping to Europe lower than 100ms?

I'm noticed I was getting bounced email errors from a company I was sending email through and I further investigated this by running a dnsreport on my domain.
Turns out that it fails at Acceptance of NULL <> sender, Acceptance of postmaster address, and Acceptance of abuse address. The domain that I ran a test on is using a new IP that I had recently added to my Direct Admin server. None of the other domains on my server are having issues like this.
Is is possible that I need to do something to enable these new IP addresses in exim? I mean, exim obviously responds to that IP address, but it seems to be having some issues with it.
I have a cPanel server with 4GB RAM
My server hangs time to time, once or twice a day. This is the last status when it happens.
Server Load 75.90 (2 cpus)
Memory Used 92 %
Swap Used 65.78 %
When I was still inside SSH when it happens, the processes I can see inside "top" are a lot of httpd processes.
So I "killall -9 httpd", I had to do it 30~40 times
#killall -9 httpd
#killall -9 httpd
#killall -9 httpd
x 30~40 times until no pid process found & the server load is back to normal.
Before that, I check httpd fullstatus, they look very normal, same goes to what I see inside WHM Apache status & cpu usage status.
At first I thought it was a memory problem after consulting with a server admin, so I replaced all 4GB new ram stick (such a waste)
This is my free -m
total used free shared buffers cached
Mem: 1998 1903 95 0 45 542

Not good ....
I got 5 wordpress and 5 statics website on this server and 100 visitors by 24H00 each day.
Question 1 : Why the memory is so low and the swap so high ?
Question 2 : Why i don't find high usage process in top command ?
Question 3 How can i resolve this problem ?
My server is very slow, High CPU, High Apache load....
I got a new server and i had setup a script on it.
No server tweaks has been done.
I run a filehosting site so it gets very slow when traffic is high.

I dont know much about server managment...
how to fix this so server doesnt go slow?
I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
My current server stats:
Dual Xeon 5130
4GB RAM
250GB
50 Mbit/sec
CentOS 3.9
Website traffic stats:
15,000 visitors/day
150,000 pageviews/day
Serving videos
I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.
I am running in a High load problem lately. I have one of those cheap 1and1 servers which was running fine until 2 weeks ago. Once I rebooted accidentaly, it did not come back with some unrepairable kernel errors and I had to re-image it.
I chose to reimage the server with CentOS 5, for better support. The new re-image worked fine for some days, at least so I thought and now I am having high loads. The server crashes if not monitored every moment as the load is unpredictable.
Just a restart of the Apache will bring the server back to normality, but I am not sure if it is apache or some other script to be blamed.
I have beeing monitoring through apache server-status, but I cannot organize something unusual in the high load moments.

So my server is "unresponsive" for abour 18 hours, burst net didnt answer my tickets and I dont know what to do. Ive been with this setup for almost 5 months with no problems, No changes have been made to hardware or software.
Im using Centos 5.0
I am doing the Security Check provided by Config Server Firewall.
It is giving me 3 errors, and I want to fix them, so here they are.
Check /dev/shm is mounted noexec,nosuid
/dev/shm is not mounted with the noexec,nosuid options (currently: none). You should modify the mountpoint in /etc/fstab for /dev/shm with those options and remount
On this one I actually went and added the noexec,no suid options. Here is what i've got configured and what it looks like. (it's most likely not correct so help correct it.)

Check /etc/named.conf for DNS recursion restrictions
You have a local DNS server running but do not have any recursion restrictions set in /etc/named.conf. If the named process is using this configuration file, then this is a security and performance risk and you should look at restricting recursive lookups to the local IP addresses only
Check dovecot weak SSL/TLS Ciphers (ssl_cipher_list)
Cipher list []. Due to weaknesses in the SSLv2 cipher you should disable SSLv2 in WHM > MailSever Configuration > SSL Cipher List > Remove +SSLv2 or Add -SSLv2
Alright so this one I followed the instructions, and i've got everything set correctly but it still shows up on the thing. I don't think the ssl_cipher_list is even available in WHM
I don't know much of anything about server settings or errors, so I need your help. Recently one of my servers have been getting a lot of 500 error messages, and I can't pinpoint the reason or replicate the error on my end. I did some Google searching and although I found out in general what a 500 error is, I still am not clear on what exactly causes them or how to reduce them. Could it be caused by intense amounts of traffic? Is the server just being overloaded?
Also, I see that my server is throwing a lot of 404 errors for a variety of URLs on my site, however when I visit the URLs specified by the error log they work fine for me - seems like only sometimes for whatever reason the server can't find/access them and throws a 404. Again, I can't replicate it and have no clue how to fix it since the list of 404 URLs work fine when I type them in.
I have a VPS account with an hosting site. For the past 2 days i have done a lot of uploads. I have 25+ sites on this account. Today when i try to login into my sites via ftp, its showing ftp login failed for all sites.
The hosting company is still sleeping on my queries regarding this matter.
Interestingly logins for WHM & cpanel for all sites are working fine.
Any experienced members plz guide me on how to get the ftp working to upload files to my sites.
I see this in the domain error logs...

When i go to dnsreport.com , i get Fail in Missing (stealth) nameservers
Quote:
FAIL: You have one or more missing (stealth) nameservers. The following nameserver(s) are listed (at your nameservers) as nameservers for your domain, but are not listed at the parent nameservers (therefore, they may or may not get used, depending on whether your DNS servers return them in the authority section for other requests, per RFC2181 5.4.1). You need to make sure that these stealth nameservers are working; if they are not responding, you may have serious problems! The DNS Report will not query these servers, so you need to be very careful that they are working properly.
ns1.mysite.ws.
ns2.mysite.ws.
This is listed as an ERROR because there are some cases where nasty problems can occur (if the TTLs vary from the NS records at the root servers and the NS records point to your own domain, for example).

This is the third time I got this message. My server is often down that SIM pretty much restart httpd, named, etc. every 2 hours.
I had no other explanation for the problem.

Here's the strange thing. The part that says "another server IP of mine" are two different OTHER servers of mine, BUT do not have cpanel nor part of the cluster. What could it be?

How to correct these errors?
On a cpanel / centos box:
We are facing with a strange issue about URLs. At any web site in our reseller account in php pages when we add http:// or http%3A%2F%2F to the URL as a query string server returns Internal Server Error 500.
For example when I try to access such page /index.php?q=http%3A%2F%2F[url] or /index.php?q=[url]I get this error. Is there any misconfiguration about PHP or Apache at server or what can we do to solve this problem?
Server uses PHP 5.2.9 / apache 2.2
Is there a way I can get more error messages with exim? I'm trying to log in using plaintext smtp authentication and all I get is this:
