For the past couple of days, I've noticed that there is alot of apache processes running in the "D" state and that my IO wait is up to %80. I straced one of the processes and the result is its locking on a php session:
2 of our our servers are suddenly experiencing high Wait I/O Times, and high Load Averages during the backup process. During this period the Plesk grinds to a halt, sometimes crashing out completely (although SSh is still possible. We have been in talks with our server suppliers (assuming this would be node related) however they have done a lot of testing etc. and categorically state the node is fine , with no other users affecting it.
STEPS TO REPRODUCE : We backup the server using the scheduled backup service and Wait I/O immediately goes up.
ACTUAL RESULT: Plesk downtime / Website downtime
EXPECTED RESULT: No downtime, successful back up
Some other info : All other processes (MYSQL, apache, Nginx etc) are all running between 1 - 10%
Partition "/usr" utilization 4.2% used (1.81 GB of 43.3 GB) (?) Partition "/var" utilization 50.6% used (61.8 GB of 122 GB) (?)
We are struggling to identify what has changed on the server that would cause this sudden change.
Looks like Im not the only one being canned for alleged "black hat seo, scaping" reason. I have no idea what that was about? Blogda that used RSS feeds? What bothers me the most is lack of response from them about giving be access to get data for my sites. Terri from DH just deleted my support tickets. Does anyone have other contacts at DH? I was being a*hole or anything, just asked what exactly did I do wrong and get access to db and content.
I have Apache2 installed on my dedicated server. I would like to install a mod / configure my Apache Server in order to limit simultaneous connections / IP.
The thing that I want is that for example if I want a maximum of 2 simultaneous connections / IP, when that IP reaches the LIMIT, I would like to delay its next request, and NOT display him a 503 error like most mods DO.
I've ordered server from LeaseWeb two weeks ago and still wait for the server setup. Its looks to slow for me - we are used to wait only a few hours for servers setup in datacanters in the US.
I'm afraid that such slow response will be also in response and level of the support. Do you think I should cancel this service and look for other provider in Europe? If yes please suggest such provider.
I've paid in advance by paypal for 3 month(~ 500 EURO). Do you think I will be able to cancel that payment?
I'm with one of the big shared hosts. Support is patchy at best, which isn't a problem until you require help at which point it's agonising as you have to wait an age to get an unsatisfactory response.
At the moment the server I'm on is suffering from consistent outages (it's been up and down over the last few days). Support has been hard to get hold of at times (right now my site is completely unacceptable for me and there's no-one tending the live support chat - which is the only chance of getting a prompt response).
My question is should I be actively looking to improve my situation (it's amazingly frustrating to spend the best part of a day doing small updates, which because of instability, take hours instead of minutes) or should I just wait until it blows over (to be fair server issues tend to be fairly infrequent, but they do flair up every so often). I can't really afford to pay that much more than I am (say $20-$50 a month max) so am I stuck with shared hosting or is there anyway to pay a little more (my current package costs around $10 a month) to get better support and stability?
After a initial look around would something like MediaTemples GS or the low end MediaTemples dedicated virtual service be suitable? The pages do have moderate database use (a few forums and galleries) and use around 50GB a month bandwidth (which would climb slowly in future months)?
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 ?
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.
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 have a large survey (I use phpsurveyor) on my reseller webdomain running. It takes about 30 minutes to fill in the complete survey. After 24 minutes my respondents get a session error and their data is lost.
Code: Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/myhope/public_html/pro/index.php:1) in /home/myhope/public_html/pro/index.php on line 2
It could've gone into the php section as well...I think.
I got a dedicated server 2 days ago, but the "session.save_path" is not set. What I did was create a "php.ini" file, put the following code into it and uploaded it to my public directory.
When i try to login my linux server from GUI i put my username "root" and then put the password, i am not able to login and getting following error
"Your session only lasted less then 10 sec. If you have not logged out yourself this could mean that there is some installation problem of that you may be out of disk space. Try logging in with one of the failsafe sessions to see if you can fix this problem view details in ~/.xsession.error file "
when I install Joomla, it said session.save_path = /tmp is unwriteable. however, following phpinfo(), the session.save_path on server is /tmp, and all my php sites are working fine, I can see many sess_ files in /tmp. That means the sessions are still written into /tmp by user apache, is that correct?
so, why Joomla instalation saying it's unwriteable? i am on a linux server
I had done a program in early 2006 for a site in php-mysql. At the time of doing the code, The code written was not so standard and it contained uninitialized variables used for include file paths (eventhough values are assigned to it before using) and the "sess" folder was created within the website folder. Also the parameters for the SQL query were not escaped, but everything was working fine.
And now i was informed that the insecure code in my program caused the server crash and i have to pay the penalty for the same. Can anyone let me know whether the below code / keeping the session variables within a folder inside the /www/ will make the sites hosted on the server where this program runs to stop/crash for ever ?
------------------------------------------------------------------ function update_region($id,$regname,$regcom) { $query = "UPDATE taxregion_mast SET taxregion_name = '". $regname."', region_comments = '". $regcom."' WHERE region_id =" .$id; mysql_query($query);
Is it possible to have 1 session under XXX.XXX.XXX.XXX IP and the 2 session under a different IP allocated by your DC?.
The box is in Europe ..I need to log-in one session and download some files from a server so whenever the master sees it will see one IP and the other session from another.
Two of the reasons I need this done is 1. privacy 2. avoiding of buying another box.
I've come across an issue where our users are not logging out of their terminal services session properly. Whether via TSWeb or MSTSC (remote desktop), if they close the browser or RDP window using the x it keeps the session alive for upto 1 minute.
The problem with this is that we use terminal services to host an application for users who can't install it, so other users that login (using a generic username and password) are adopting/hijacking the original session and seeing someone elses data.
Does anyone know of a way to force a new session each time a user connects to RDP? Whether via TSWeb or MSTSC (remote desktop)?
if it's possible to log all ssh commands to a file by session. For example, if I log in as user 'test123', once I close the session, all commands I ran will be saved to a file and either emailed to my server logs email address or saved to a file.
I am assisting a client who is linking to an online calculator, he is putting a frame on top of the calculator page, so people will still see his information. However, for some reason he is getting a Session Timeout Error in IE.
I don't get this error in Firefox using this method, or ever going to the direct page in IE.
Let me give a better explanation:
If you visit: [url]
Just put in a fake name and email, it loads a frame at top, and then the online calculator, which is this page: [url]
Why I am getting a Session Timeout? Is there a better solution. I never get the same error if I go directly too: [url]
We want a frame or better solution because we still want the contact information to be in front of the consumer.
Does this maybe have to do with a cookie and frame?
I have a website where people perform a number of tasks, saving some data to temporary session files. If the user is idle for a certain amount of time, then performs an action, his/her work will be gone.
I'd like to set the sessions to never expire, so that only a browser close would delete the temporary files.
I've tried looking around in the IIS manager, but I cannot find a way to do this.
