I'm using 2 accounts at jabber.ccc.de, maybe this causing the issue?

The experimental db4o backend was never production ready. You should upgrade to the sqlite backend of Smuxi 0.12-dev.

Smuxi can deal with multiple connections to the same server/network but not with the on-disk chat history backed by db4o, the sqlite backend supports multiple reader and writers.

sqlite <-> db4o: So, does this change, when I switch in the settings from "Volatil" to "Persistent" ?

I couldn't find a documentation, what's exactly the difference between the two settings. Also the different buffer line settings should be explained somewhere more detailed. It's a little bit confusing at the first view...

Yes Persistent uses db4o as backend and that threw the exceptions you have reported.

I agree, I sometimes also forget what each setting means related to the buffers :-D

Smuxi's message buffers are now documented: https://smuxi.im/faq/usage/message-buffer-settings/
