Messages stuck in queue

[white8]

I'm running 5.0.12 on CentOS 5.2 and periodically have messages get stuck in the queue. The only way to clear the pulg is to reboot the server. Requeueing the messages and restarting Zimbra have no effect.

Please check the other Log Files - Zimbra :: Wiki for any error messages.

Would you also please update your profile with the output from

su - zimbra
zmcontrol -v

I took a look at the otehr logs and didn't see anything.

On a side note, as luck would have it I have 5.0.10. Is there a How To for an upgrade or better yet a Yum repository? I'm not experienced with Linux and hate to kill a production server.
