I've been toiling over a test plan for some time. Soon as it gets at least comparable to the one on the Wiki, I will post/update it. I think more people should be involved in simple testing, and not just running servers, but that's the QA in me coming out.
Meanwhile, I have had little issue with 941 for weeks on FC4. No freezing, but occasionally I'll get weird messages when I zone that look like paths to the quest scripts (perl5.8/something.pl etc). I have not reported it because when I get logging set up, it stops happening.
