Default multiple zmlogger instances running

I'm running 4.5.9 of the Network Edition. I've been having a lot of trouble with slow performance...lots of "cancel request" dialogs in the web interface, client timeouts, etc. The server had dual quad core processors, 4 gb ram, a 1terabyte of raid 5 drives. Last week I opened a trouble ticket and one of the Zimbra techs helped me with the issue...it didn't 100% resolve it, but it seemed much more stable. The problem was that there were multiple zmlogger instances running. Performance got a bit better after the extras were stopped.

Today I was getting timeouts again. And there seems to be 4 zmlogger instances running. 2 questions:

1) Why do they keep coming back, and how to I prevent it from happening without just checking the server processes all the time.

2) how do I know which one of the 4 to kill? Also, can I just kill the process or is there a more graceful way to do it?

[root@localhost ~]# ps afx|grep zmlogger
18930 pts/0 S+ 0:00 \_ grep zmlogger
10120 ? S 10:43 \_ /usr/bin/perl /opt/zimbra/libexec/zmlogger
7897 ? S 5:17 \_ /usr/bin/perl /opt/zimbra/libexec/zmlogger
12338 ? S 0:20 \_ /usr/bin/perl /opt/zimbra/libexec/zmlogger
4531 ? S 0:01 \_ /usr/bin/perl /opt/zimbra/libexec/zmlogger

thanks,
altimage

Don't know without knowing the details of your support case. I'd suggest you re-open that case and follow-up with the fact it's happened again.

The quick answer is to stop the logger and kill what's left or shutdown Zimbra and kill anything that's left.

Which operating system is installed? Has this problem just started happening and have you done any system updates to the o/s?

It's running RHEL5. It's a new server, probably 2-3 months in production so there haven't been too many OS updates...maybe some basic things through YUM but nothing kernel realted to too big.

We've got about 1200 mailboxes on the server so we've always struggled with performance...that's why we moved to a bigger server a few months ago. This is the first I've been aware of multiple zmlogger instances though.

How much RAM does this server have and you haven't done the update to RHEL5.1 then?

In any case, I'd suggest your best course of action is to reopen your original support case on this problem - that will get you the quickest help.

It's got 4GB or RAM. No we haven't upgraded to RHEL 5.1. I replied to my closed support ticket...I'm not sure if that will "Reopen" it...I didn't see a "Reopen" button...I guess I could just start a new one. Anyway my case number is 00017442.

thanks,
