Somer Error?

[vivek]

Hi there!

I just installed litespeed on my new dedicated server running on CentOS 5 and cPanel.

But I am getting a mail, so many times, and here is the error


At [29/Mar/2008:01:03:01 -0400], web server with pid=21612 received unexpected signal=9, no core file is created. A new instance of web server will be started automatically!


I am getting the same mail every minute.

I am on cPanel Stable version, so I disabled the wrapper script.
Any idea, about this error ?

Vivek

You should enable the wrapper script even though cPanel is stable version...

 

[vivek]

You should enable the wrapper script even though cPanel is stable...

Then why there is the "option" for wrapper script ?

 

[anewday]

I think it's because not everyone uses the cPanel 11 version that affects LSWS.

 

[vivek]

I think it's because not everyone uses the cPanel 11 version that affects LSWS.

As far as I know, everyone is using version 11, if they are using cPanel.
Because I heard , cpanel.net is not supporting cPanel 10 now.

 

[ts77]

and not everyone is using an hosting control panel at all.

I am on cPanel Stable version, so I disabled the wrapper script.
Any idea, about this error ?

cPanel was killing lshttpd with "-9", the wrapper script should fix it.

 

[vivek]

cPanel was killing lshttpd with "-9", the wrapper script should fix it.

I dont think so , because the server is new and only 1 account is there.

 

[mistwang]

Signal 9 is SIGKILL, it won't be trigger by anything other than sending by anther process to kill the process off.

Hi, we seem to have same issue here and the wraper script seems to not work.. just installed litespeed with cpanel 2 days ago:

This is happening every 1 minute.

 

[mistwang]

Maybe you need to uncheck "monitor httpd" under service manager page.

 

[k3oni]

Maybe you need to uncheck "monitor httpd" under service manager page.

I hav already did that, also disabled Auto Restart and LFD on the server, but this is still happening.

Any ideas?

 

[mistwang]

check if there is any cron job that tries to stop lshttpd process, there are some security scripts doing that.

 

[k3oni]

Thanks for trying to help here, seems that there is no cron job.

Interesting part is that once is stoping the listeners on a few IP's, next time on others, another time my them up, so it does not do a restart on all the IP's every time.

 

[k3oni]

We would really like a solution to this, i can provide whatever logs needed. This restarts are making the sites show as down and need a refresh to bring the sites back up, not best solution when the client is a hosting company.

Please advise, any help would be appreciated, thank you!

 

[mistwang]

You need to find out which process want to kill lshttpd.
PM me your server login, I can take a look if you want.

A cron job added by root user is killing all processes running as nobody every minutes. the script is /root/sks.pl

 

[k3oni]

Thanks for that.. seems that i missed exactly teh script that was put in place by us.. great . Will have to modify that as it is working correctly only on Cpanel with apache.

Thanks again George!

check if there is any cron job that tries to stop lshttpd process, there are some security scripts doing that.

Next time, please look harder along what I have suggested.
