Problems I'm getting with 5.5

[jbb]

Here are the main problems I'm getting with my 5.5 server (running on gentoo linux if that matters) :-

The main one is with zoning. About 50% of the time when any character zones the client just hangs. Most of the time restarting the client gets you in, but I eventually this doesn't work any more and it's impossible to log that character in at all any more.

After leaving the server running overnight all the zone servers died complaining that there were too many connections to mysql.


ANy advice on how to track down what's causing these problems (or even better some solutions!) would be great.
