[ http://jira.jboss.com/jira/browse/JBTM-213?page=all ]
Jonathan Halliday updated JBTM-213:
-----------------------------------
Affects Version/s: 4.2.3.SP2
(was: 4.2.3.SP1)
Threads in endless loop in TransactionReaper.
---------------------------------------------
Key: JBTM-213
URL: http://jira.jboss.com/jira/browse/JBTM-213
Project: JBoss Transaction Manager
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: JTA Implementation
Affects Versions: 4.2.3.SP1
Reporter: Phillip Thurmond
Assigned To: Jonathan Halliday
Fix For: 4.2.3.SP2
After generating a load against JBossAS 4.2 beta1, the cpu is pegged at 100% even after
the load has stopped. A thread dump reveals several threads at
TransactionReaper.insert(). These threads are all doing a WeakHashMap.get(). Looking at
TransactionReaper, I believe this is caused by unsynchronized access to the _timeouts
WeakHahsMap. This is line 324 in TransactionReaper.java.
