503 Service Unavilable After with to 3.3.10 , lsphp5 Fresh Installation

[vivek]

Hello

I recently installed a fresh copy of lsws with php 5.2.4. Everything is working fine.

But since then one of our website , which is using Jooma, is showing 503 error

Check HERE (http://www.youthkerala.com/index.php?option=com_rsgallery2&Itemid=128&page=inline&id=494) and try to post a comment below.

I tried to increase the process soft and hard limit to even 1000 from the default vals 200. , but seems not working

Mistwang, you must be knowing why I recompiled and reinstalled litespeed.

Any help to fix it ?

Vivek

I tried with both suPHP enabled and disabled.

[mistwang]

enabled suEXEC, and strace lsphp5 process to find out why, maybe the process crashed, or missing a required PHP module.

[vivek]

enabled suEXEC, and strace lsphp5 process to find out why, maybe the process crashed, or missing a required PHP module.

suEXEC is already enabled. then what to do ? Can you take a look at this ?

[vivek]

Now,

What is this mail ?

lfd: Excessive resource usage: server (492)

I cant find any option in External App with 100M . How do I increase it ?

[mistwang]

Memory soft/hard limit for lsphp5 external app. I am not sure it is limited by the system or not though.

Also need to check why it use more than 100MB for a joomla site, allocate too much memory for opcode cache or something else.

I think this email is sent by lfd, 100 MB probably is a configuration for lfd script.

[vivek]

Any reply for the first post ?

[mistwang]

did already.

strace lsphp5 process to find out why, maybe the process crashed, or missing a required PHP module.

[vivek]

I dont know how to strace etc, Please help me.

[vivek]

I cant believe that the litespeed's default configuraiton isnt good for even a joomla website

A user can't register for a new account or cant login with the existing account

http://www.youthkerala.com/index.php?option=com_secureregistration&task=register


It shows 503 service unavailable

[mistwang]

find out the pid of the suexec lsphp5 process for that users.
then do
strace -p <pid>

[vivek]

[mistwang]

this is a idle PHP process, you have fire a request that produced 503 error, and the PHP process is serving the request.

[vivek]

:confused:

[mistwang]

After you start to strace the process, send a request that result in 503 error, strace will dump all system calls involved with processing that request. And you should be able to find out why PHP failed to process that request based on the output.

It might be a memory limt problem. You can try increase the memory soft/hard limit for lsphp external app. If it deos not help, you may have to rebuild you PHP binary again matching the configuration parameters used by Apache mod_php.

[vivek]

Soft/hard limit increased to 1GB/2GB . Still same.
As far as I know, I built the php binary using the same parameters of apache mo_php. Please explain what do you mean by this. :(

[mistwang]

It is a PHP internal problem.
You can try GDB the PHP process as well.

gdb /home/lsws/fcgi-bin/lsphp5 <pid_of_lsphp>
(gdb) cont

Then send the problemtic request, gdb will stop at the crash point, then type command "bt" from gdb. It shows you PHP crash point, with this information you should be able to find the module that cuases the problem or file a bug report to PHP group.


you need to compare the phpinfo page produced by apache mod_php and lsphp, there should be something different.

You can also try disable PHP suEXEC see if the problem goes away, if it does, there is a permission problem somewhere.

Would also recommend using Pastebin (http://pastebin.com/) to show us the log.
