ejabberd memory leak

Steve — Wed, 14 Jan 2009 11:00:41 +0000

If your ejabberd seems to leak memory it might result out of this bug in erlang’s mnesia database. You can easily find out by starting a remote shell to your running ejabberd and whatch results for the following command:

lists:foldl(fun(Tab, Acc) -> ets:info(Tab, memory) * 8 + Acc end, 0, ets:all()).

The bug is fixed at erlang OTP R12B5.

EDIT:
A good description of the problem can also be found at Yaws, Mnesia stress test notes.

ejabberd mysql drivers for debian and ubuntu

Steve — Wed, 14 Jan 2009 10:30:36 +0000

Debian (and ubuntu) packages for ejabberd don’t contain drivers for mysql. If you want to connect your ejabberd to mysql you need to get those drivers separately from the external ejabberd modules repository and compile them on your own.
For convenience I’ve built a debian package containing the precompiled modules:
ejabberd-mysql-20090114_1-2_all.deb

Note: this package is not of the usual quality you’d expect from an official debian package. It’s just an alien’ed tarball containing the drivers at the right place (i.e. ‘/usr/lib/ejabberd/ebin’).
