    Repeating server crashes with high threads

    Hi

    My zarafa sever became unstable this afternoon. It runs out of memory quickly and then dies. I found it starts using all allowed threads and this is the only error it shows:

    Thu Jun 9 01:37:07 2016: [error ] Disconnect from LDAP because of search error Timed out, there are a lot of 'end of sessions' arround that.

    The server runs Ubuntu 12.04 with Zarafa 7.2.3

    What should I check?

    I can't trigger this situation by generating traffic. It does not clear either when I shut down apache. I have to kill the zarafa-server to get back to a running state

    I disabled z-push at 3 this night and the crashes stopt.... So that seems to be the culprit. Running the latest version 2.2.9

    Thank you Felix, however there seems to be a dependency issue in the Ubuntu release:
    zarafa depends on zarafa-backup-plus (= 7.2.4.10-82.1); however:
    Package zarafa-backup-plus is not installed.

    I installed it with ignore dependencies

    Hi Felix, the problem is still there with 7.2.4-rc1. Crash every 30-90 minutes. Memory usages is fairly constant and that shoots up.

    Hi,
    can you please take a look at
    it is LDAP and segfault related, which quite resembles the case that you are describing
