AsynchStore.addWork() never leaves overlfow lock loop
-----------------------------------------------------
Key: JBTM-840
URL: https://issues.jboss.org/browse/JBTM-840
Project: JBoss Transaction Manager
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 4.14.0
Environment: Ubuntu 10/Java 1.6/MySQL 5.5/JBoss JTS 4.14.0/Spring 3.0/Hibernate
3.6
Reporter: Tom Waterhouse
It looks like somehow when using CacheStore with JBoss JTA it is possible to get into an
endless loop. On the server our app is deployed one cpu is pegged at 100% usage. A
thread dump revealed that a thread is executing AsyncStore.addWork() and never leaves
(thread dump shows line 330, _overflowLock.wait()).
Our cache size is set to 200k.
Here is from the thread dump:
