    Default java.io.IOException: Too many open files

    I'm running version 5.0GA on Debian. Every 2 or 3 weeks my Zimbra install would stop responding, and I'll find the below messages.
    Has anyone else seen this?

    Code:
    2008-01-24 05:58:24,802 WARN  [btpool0-3 - Acceptor0 SslSelectChannelConnector@0.0.0.0:7071] [] log - EXCE

    check your ulimits (ulimit -a). i think from memory -n resets files?

    Hrm.. ok, I changed the open files limit to 65536, up from the 1024 default.
    Hope that takes care of it.
