Hi,
I have using MySQL Connector/NET (MySql.Data.Dll) to connect to MySQL from my Mono app which runs on Fedora Core 7.
My program has about 150 simultaneous users (it's a chat server) and queries the database a fair bit.
It crashes anywhere from 10 minutes to 2 hours running with this error:
Stacktrace:

I've tried using connector/net 1.0.7, 1.0.9, 5.0.3... still same problem
Any ideas? I've been stumped for months.
