webmaild CMDs building up over time affecting performance

[Dean_ONP]

One account on our cPanel server has approx. 300 mailboxes.
Most of these users access their email via the webmail.

Over time there has been a build of webmaild commands from this account.

> ps -es
will show the following (have included only a few as example):

This looks to be impacting on server load and chewing up available memory causing other processes to end due to lack of memory.

Killing the webmaild processes resolves the issue
> for i in `ps -ef |grep petitjo+|awk '{print $2}'`;do kill -9 $i;done

But of course these start to build up again.

Any ideas how I can prevent these from building up?

Hello,

Could you open a support ticket using the link in my signature so we can take a closer look to see why these processes are hanging?

Thank you.

Thanks Michael

This has stopped happening since latest update was installed.
Have monitored for a few days and all looks good.
If I notice this recurring I'll log a ticket as suggested.
