JDBC problem

[Reynir Þór Hübner <reynir@hugsmidjan.is>]

I'm running an engine with 15 databases, with fair amount of load. Every 
4-5 days I'm getting error like this from the java side and the 
application stops working (and wont come back unless I restart) :

java.net.SocketException: Broken pipe

Does anyone know what this is about ?
I'm using Red hat Enterprise, and all the correct JDBC drivers etc.
