408.shtml error and then litespeed stalls

[pguy]

Hello,

We are seeing the following error repeatedly.

2009-04-05 06:17:55.950 [INFO] [203.212.239.28:53692-0#APVH_xxx.com] File not found [/home/xxx/public_html/408.shtml]

Can't seem to figure out why - the error shows up, then LS spirals out by running too many processes and the only way then is to kill lsphp & then restart litespeed.

any leads?

You need to check why the request takes so long, usually, it is a PHP/MySQL issue.
Also, try our 4.0.1 release package see if it helps or not. Just change the version number in the download link to get it.

Hi, I tried. It helped for a bit and then again the server spiralled out. This time though it was able to cut on the processes much faster than prev times. But the problem still exists ..

I still see many 404.shtml errors in the log with 4.01.

On the stats page, when the server went out of control I saw the following statistic

EAProc Idle - 170

[mistwang]

You probably configured the number of process of that external application too high?
Show me the configuration.

[pguy]

PHP_LSAPI_MAX_REQUESTS=200
PHP_LSAPI_CHILDREN=200
LSAPI_MAX_IDLE_CHILDREN=60
LSAPI_AVOID_FORK=1

Process Soft limit 500
Hard Limit 750

PHP_LSAPI_CHILDREN is way too high. Start with 20. You should increase PHP_LSAPI_MAX_REQUESTS and lower LSAPI_MAX_IDLE_CHILDREN a lot more. What value did you set for Instances?

[pguy]

Modified settings to

PHP_LSAPI_MAX_REQUESTS=300
PHP_LSAPI_CHILDREN=30
LSAPI_MAX_IDLE_CHILDREN=20
LSAPI_AVOID_FORK=1

Instances, set to 1

Lets see how this goes. Anything else I need to check?

I think you should increase PHP_LSAPI_MAX_REQUESTS a lot more and lower LSAPI_MAX_IDLE_CHILDREN What's the value for Max Connections? I set mine to match PHP_LSAPI_CHILDREN
