[jboss-user] [JBoss Cache: Core Edition] - Re: BerkeleyDB Deadlock Exception from JBoss Cache Loader: B

[niuxuetao_fiserv]

Maybe something useful to give:

Now I use 20 threads doing the same job (setting ockAcquisitionTimeout="4294967", all the rest configuration is the same as I pasted before), I experience a phenonemen which seems to be a "true deadlock" since no threads are running (jobs in the Threadpool Executor's queue are undone) and the cpu usage is zero. Then after a while, like 1 minute, one of the threads threw this:

Have you seen anything like this?
