Potential deadlock with ClusteredCacheLoader
--------------------------------------------
Key: JBCACHE-1103
URL: http://jira.jboss.com/jira/browse/JBCACHE-1103
Project: JBoss Cache
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Cache loaders, Clustering
Affects Versions: 1.4.1.SP3, 2.0.0.CR2
Reporter: Brian Stansberry
Assigned To: Manik Surtani
Can occur if
1) Thread1 on node1 is trying to get(fqnA) which is not in-VM, so the CCL tries to do a clustered get. The CacheLoaderInterceptor lock for fqnA is held at this time.
2) Thread1 blocks in FC waiting for credits.
3) Replication message for fqnA arrives from node2.
4) IncomingPacketHandler thread will block waiting for the CacheLoaderInterceptor lock for fqnA.
5) FC credits cannot arrive, so we deadlock.
Stack traces below show this.
