    Default Unstable

    Hi,

    I have not touched any config. of the server recently. After working for some days, I found the mailbox was stopped suddenly today. Users could not check email. The direct method was to restart the service. After I checked the log, I just found the SASL login auth. failed suddenly. Afterwards, the mailbox service was stopped. It's not a good day. I am afraid of the same event happen later without control. What I have to check next?

    Default java.lang.OutOfMemoryError

    This may help.

    Edited:
    Found some post about the OutofMemoryError. May the following information help.

    Number of Users: 10
    Box: 2.4Ghz Intel based Server w/ 1Gb Ram

    Since all users are new. They did not intensively use the Webmail yet. Their normal operation is just SMTP + POP.
    Most of them just ten somethings of their mailbox size.

    Can you reproduce this error? Is there anything else running on this box?
    Looking for new beta users -> Co-Founder of Acompli. Previously worked at Zimbra (and Yahoo! & VMware) since 2005.

    I can't reproduce this error. Since it was happened suddenly. The server is a clean installation from FC4. The traffic is quite low. No special application is running except Zimbra.

    is there anything under LmtpServer-2976 in the /opt/zimbra/tomcat/logs/stacktrace.<pid> generated when you restarted the mailbox?

    I could not find that there is any stacktrace.<pid> file created today which I restarted the service this morning.

    Code:
    [root@mailsrv logs]# ls -l | grep stacktrace
    -rw-rw-r--  1 zimbra zimbra  85350 Feb 14 12:45 stacktrace.13261
