Can't say I've ever seen this before. I'm standing in Frostfang, literally haven't moved since I logged in. Chatting on IRC, working on spells in the editor. I went to do some commands and got no response. When I pulled the console to the front, I saw a sea of red:
Nothing crashing, just puking. And this is your same ol Frostfang everyone has now. So, no idea.

Jab and I basically determined during the zoneserver rewrite that our read/write mutex locks were unreliable. I have a mach rewrite done but we're still doing more testing on it so not calling it fixed yet, but that's probably why this happened rarely.

I think we all agree in an equal hatred for our Mutexes I'm sure whatever you guys do will be much better in the end.
