JESS: Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

[jo]

Hi

I got following error, which surprises me as I try to keep the amount of facts 
to a minimum. 

Can I detect this condition *before* it is about to happen ? Any ideas on how 
to prevent this ?  

30m is really not that long :(
