[jboss-user] [JBossCache] - Write lock is not released

Hi all, we have JBoss 4.0.2 , JBossCache 1.2.2 and Hibernate 3.1. Isolation level = repeatable read Ocasionay we observe a following in logs: 1) thread x starts a transaction and obtains a write lock on resource A 2) ~30 mins go by 3) transaction in thread x fails to obtain a _read_ lock on resource A, since write lock is already held by thread x: anonymous wrote : | [ReportDataTaskRunner-20521017-1] - Transaction failed due to exception | org.hibernate.cache.CacheException: org.jboss.cache.lock.TimeoutException: read lock for Attribute#4558 could not be acquired by <zzz:4256>:162303 after 15000 ms. Locks: Read lock owners: [] | Write lock owner: Thread[ReportDataTaskRunner-20521017-1,5,jboss] | , lock info: write owner=Thread[ReportDataTaskRunner-20521017-1,5,jboss] (activeReaders=0, activeWriter=Thread[ReportDataTaskRunner-20521017-1,5,jboss], waitingReaders=0, waitingWriters=0, waitingUpgrader=0) | This lock stays forever. I'd appreciate any hints on this. Thanks in advance, Stas. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4062019#...
