[infinispan-issues] [JBoss JIRA] Resolved: (ISPN-277) LRU data container endlesly looping or exhibiting heavy contention

LRU data container endlesly looping or exhibiting heavy contention ------------------------------------------------------------------ Key: ISPN-277 URL: https://jira.jboss.org/jira/browse/ISPN-277 Project: Infinispan Issue Type: Bug Components: Eviction Affects Versions: 4.0.0.CR2 Reporter: Galder Zamarreno Assignee: Manik Surtani Priority: Critical Fix For: 4.0.0.GA Attachments: td2.txt Something around LRU container is not working fine. The attached log from an concurrency test in the 2nd level cache shows that in 3 thread dumps taken over 30 seconds appart, UserRunnerThread-5 is stuck in: "UserRunnerThread-5" prio=10 tid=0x6f65bc00

However, once LRU is switched to NONE or FIFO, the test runs in 5 seconds. So, something looks fishy with LRU.
