Subject Derby Stack Overflow releated to deadlock
Date Sun, 18 May 2008 02:04:29 GMT
(Sorry, I forgot to put a Subject on my last email. Here it is again, with a Subject)
Hi,

I am having another issue with deadlocks. I put this in derby.properties to get more information:
derby.locks.monitor=true
derby.locks.deadlockTrace=true
derby.locks.deadlockTimeout=1
derby.locks.waitTimeout=1
derby.storage.pageCacheSize=40


But
then I see this StackOverflowError in derby.log. Anyone know what the
problem is? The stack trace below goes on and on and on (I truncated
it). Looks like Derby is stuck in a recursive call, then the stack
overflows.
