Hi everyone,

since some time I got problems with dovecot & mysql. I got the problem with version 2.0.x and upgraded to 2.1.7 to check if its gone. But its not :( The logs just tell me this: dovecot: auth: Error: auth worker: Aborted request: Worker process died unexpectedly

If I change to a sqlite setup, everything works fine.

Here are some informations. I hope someone can tell me whats wrong with my system/setup. I really dont think that this is a bug because someone else should have hit that before me.
