Increasing APC Cache Memory Size
Dec 11, 2008Right now APC shm_size is set to30 and since I am only using about 20% of the RAM in VPS, I thought it would be best to increase it a bit. Now how do I go about doing that?

Plesk 12.x / Linux :: PHP Fatal Error - Allowed Memory Size Exhausted
Feb 12, 2015I run few export procedures which take a long time ot process (lots of joined sql) and generate quite large output. Plesk 11.0.x required some php/fcgif adjustments but I got it to work.
Now I switched ot Plesk 12 and have to set it up again.
I started with Plesk / PHP Settings for this domain:
memory_limit set = 2G
max_execution_time = 600
max_input_time = 600
post_max_size = 2G
Default subscription has no setting for above values but I have added them per this domain os not sure why it ignores my 2G value?

Does Mod_cache Use Real Disk Space Or Real Memory To Locate "cache"?
May 18, 2009does mod_cache use real disk space or real memory to locate "cache"? I mean if i use mod_cache, does my vps/server will use more disk space/memory?

mod_cache implements an RFC 2616 compliant HTTP content cache that can be used to cache either local or proxied content. mod_cache requires the services of one or more storage management modules. Two storage management modules are included in the base Apache distribution:
Account Size Not Matching Real Size
Aug 14, 2008One of our resellers has an account.. When looking into cpanel, it says that that account is using 3300megs. When we go into the ftp of that account, in reality it is only using 1.3megs. This is a huge difference! Most of folders are empty.
We are using the latest version of WHM and Cpanel.

View 2 Replies View RelatedMy Consumed Space Is Keep Increasing - Do You Know Why
May 24, 2008I have bought a hosting from new hosting company.
I have total 5GB space wherein I can host unlimited domains.
When I uploaded my files ( for 4 sites ) I saw that I have used total 16 MB. But today when I logged in there I noticed that the cPanel shows that I have used total 22.75 MB
But I didn't upload anything that may take upto 6MB space
I just uploaded few images that may take maximum 100KB.
My hosting provider said this
"The extra disk space could be email messages stored on the server, mysql database files, etc... All these things are accounted for within your disk space."
But I replied that I don't use any database and I don't have any single email in my account so how that space can by consumed? Waiting for their further reply.
Increasing Server Capacity / CPanel
Apr 13, 2008I'm trying to start a website on a shoestring budget, but my programmer and host want to squeeze more out of us. We currently have a Custom VPS, w/cPanel and WHM. Everytime I try to upload a file(s) more than 10 mb, it will not go thru. My programmer told me to ask the server to increase capacity, they tell me it will cost me. My programmer says the same thing. Now if my programmer can do it, I assume it will be done through cPanel. Is there anyway I can do it myself, so for example, a file of lets say 25 mb will get uploaded? I have access to my cPanel.

VPS Disk Quota Status Keeps Increasing Every 2 Days
Aug 18, 2008I have had over 4 different VPS providers and in all of them, I was always using less than 5 gigs and most of it is from the OS and the VPS files, my website is less than 400 megs of size including the backups. For some reasons, my Disk Quota is at 8.3 gigs and it was at 8.2 gigs yesterday. My website's files are not that big and the Database is like 30 megs and the backups are compressed so they are like 4 megs. The problem is that I really don't know what files are making my Disk Quota to go up since I haven't uploaded anything or download files to my VPS.
View 6 Replies View RelatedIncreasing The Expiration Time For SSL Certificate For Exim
Jul 12, 2007I issued a self-signed certificate for Exim by running the following commands:
Code:
openssl req -new -x509 -keyout /etc/exim.key.tmp -out /etc/exim.cert
openssl rsa -in /etc/exim.key.tmp -out /etc/exim.key
rm -f /etc/exim.key.tmp
service exim restart
The problem is the certificate expires after one month. I have already edited my /usr/share/ssl/openssl.cnf with the following lines in order to increase this expiration time to one year and it worked for the SSL certificate issued for Apache, but it has no effect on the Exim certificate.
Code:
default_days = 365 # how long to certify for
default_crl_days= 365 # how long before next CRL
Should I edit another file or set it on another place? Does anyone know?

Plesk 11.x / Windows :: Increasing Server Configured Values For Client Timeouts
Sep 25, 2013The last packet successfully received from the server was 60.410.682 milliseconds ago. The last packet sent successfully to the server was 60.410.687 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'auto Reconnect= true' to avoid this problem.
View 2 Replies View RelatedCpanel VPS - Plenty Of Free Memory, But 'committed' Memory Exceeds VPS RAM
Jun 12, 2009I have a VPS. And have had an issue both when it was 1Gig and now I recently downgraded it to 768m, because I am moving some sites to a dedicated.
However, the part I am having trouble grasping is that when I look at graphs from Munin, it will typically always show 200-400MB free memory (and free -m and top agrees with munin), but Munin shows 'committed' memory that is above the total Ram on the VPS and once the 'committed' ram exceeds the VPS limit, processes start failing.
So, why is 'committed' memory exceeding the RAM on my VPS, when Munin, free -m and top all show there is free memory available?
Code:
root@server [~]# free -m
total used free shared buffers cached
Mem: 768 449 318 0 0 0
-/+ buffers/cache: 449 318
Swap: 0 0 0
Here's a graph that munin produces that shows the 'committed' memory exceeding the total memory.

AWSTATS Stats Decreasing While Webalizer Stats Are Increasing
May 23, 2008I look after a number of sites and monitor their stats. We use both webalizer and AWSTATS so we can have a comparison. Up until recently the stats for both of them where relatively the same, webalizer usually showing higher numbers as it doesn't filter bots but the progression of increase and decrease in stats was proportional. However, over the last few months a curious trend is appearing, the stats in AWSTATS are decreasing every month whereas the stats in Webalizer are increasing, the gap between them now is huge.

Increasing The Apache ServerLimit In Apache 2.2.8 Version.
May 28, 2008The Linux Server got down when the MaxClients 256 is reached.
Error Log:
"server reached MaxClients setting, consider raising the MaxClients setting"
So that I have tried to increased the MaxClients Value to 500, after changed the value in httpd.conf and restart I get following error message.
" [notice] SIGHUP received. Attempting to restart
WARNING: MaxClients of 500 exceeds ServerLimit value of 256 servers,
lowering MaxClients to 256. To increase, please see the ServerLimit
directive."
So that I tried changed the Server limit in /usr/local/apache/include/httpd.h header file. but it seems like there is no entry.
Apache Version : 2.2.8
So I have added the ServerLimit 500 entry in httpd.conf file and restart the httpd service. But still shows the same warning mesg. Please help me regarding this.

View 1 Replies View RelatedPHP And Cache-Control
Jan 27, 2008I seem to have the opposite problem of what most people complain about... I'm using some custom-built PHP scripts, the output of which is not getting cached. I want the output cached, because it doesn't change often.
If it's relevant, I'm using ob_start() to serve up a GZIP-compressed page.
I start off with a header("Cache-Control: maxage=3600, must-revalidate"). Yes, it's first, and yes, it's showing up properly in the browser.
However, requesting the page again returns an HTTP 200, not the 304 I'm expecting. It's pulling down the whole page again. It's not changing in between requests, and I'm simply visiting the URL again, not hitting Refresh. (Although it really shouldn't matter.)
