Zimbra not responding

559jwilson · Post by **559jwilson** » Mon Jul 17, 2006 9:31 am

Not sure if this is the right place for this post. But recently I have to do a zmcontrol stop/start to get the mail server to respond. When I do a zmcontrol status everything looks fine. In the logs. I see a line
Caused by: java.io.EOFException: SSL peer shut down incorrectly.
It is in the log file quite a bit but I don't know if this is the cause of the issue. I can post the log file if you want let me know. Thanks

I suppose the question would be why is your SSL shutting down.
Do you have anymore from the log? and a stacktrace might be useful.

Let me know if this help any. I afraid I don't know what you mean by stacktrace

Seems some clients are getting SSL/TLS errors when using POP. When you say the mail server is not responding can you get to the web client or is it entirely hung?
If this happens again please try this:
kill -QUIT
This should dump the threads into /opt/zimbra/tomcat/log/catalina.out. Attach a zip file of that log here. We may be able to find out *where* the problem is from that stack trace.
Also in general you should just need to run "tomcat restart" for this to clear. The full zmcontrol works but will just take longer.

When this happens you can still access the web client you just can't pull any new emails into outlook or thunderbird. I will run the command you posted next time it happens. Thanks for the advice. I will post next time I get the problem

Ok it finally did it again, I admit it has been awhile I used the kill command. It did print out a catalina.out file do you want me to post here. Also we have zimbra running under jboss and tomcat. let me know it this helps at all.

It would be better to file a bug and attach a zip file with the log details.

I believe that this can actually happen in the wild when a remote SSL client disconnects very early in the handshake. If it only happened once on your site, it's likely to be a client issue abd I wouldn't get overly worried about it.
If it's happening a lot, that's a different story.
