Services stopping randomly

[AlanWilliamson]

Just a small follow up here. I have upgraded to the latest Zimbra.

One thing to note; kudos to the zimbra team for making the upgrade process wonderfully simple! It even kept the custom ports i had put tomcat/apache too. So result.

I will monitor the system closely and if it dies again, i will respond here with any details.

thanks

Well didn't have to wait too long before it to crash again!

Its definitely Tomcat -- we have it set so the maximum email size is 10MB if thats any help.

HELP!

So tomcat is crashing -- why?

There is out-of-memory logs in the catalina logs -- but why?

Data points:

- Tomcat is started up with 607MB of memory (default setting).
- Machine has 1.5GB memory (Linux Fedora4)
- There are NO users on the system when it decides to crash.
- We have set the max message size to be 10MB
- Upgraded to the latest/greatest Zimbra release
- Total mailboxes on the system is a whopping 20!
- Trouble free system except for the last week

What can we do if someone tries to push a bigger email to the system? There is obviously an email in there somewhere that is causing the system to choke. Why did it get in there in the first place though?

Please advise -- as this is making what was a beautifully running system, completely in useable and a nightmare to manage.

Any advice people?

Have I hit a problem with Zimbra that can't be solved?

We are now on an hourly reboot cycle -- we can't keep Zimbra up, and i can confirm there are NO USERS on the system. So there is a process in there somewhere (java related) that is causing major problems.

We are starting to experience the same kind of problems. Mailbox service start to crash from time to time...zimbra was runnig fine since january...

I have same problem in the last two days. Zimbra was working fine for 4-5 moths, 4.5.4 on centos4. Mailbox service stops in a specific period, sometime between 11 and 11.15, and although manually started again it stops over and over again in this period. After that it runs normally. Can anyone help?

Guys same problem here as well. It happens randomly, not every day but from time to time. usually in the mourning. don't know what to do. we have two servers, this happens on one. any ideas?

[mmorse]

Handza have you had this problem for 7 months? (I see no other posts by you since 09-13-2007)
Have you been able to get logs from just before the services stop?
/var/log/zimbra.log, /opt/zimbra/log/mailbox.log & zmmailbox.out if you have one.

Are you still on 4.5.4? Might be time to upgrade to 4.5.11 or 5.0.5

Please post the output of:
su - zimbra
zmcontrol -v
