[infinispan-issues] [JBoss JIRA] (ISPN-1915) Memory leak in L1 manager

Memory leak in L1 manager ------------------------- Key: ISPN-1915 URL: https://issues.jboss.org/browse/ISPN-1915 Project: Infinispan Issue Type: Bug Components: Distributed Cache Affects Versions: 5.1.2.FINAL Reporter: Manik Surtani Assignee: Manik Surtani Priority: Blocker Labels: memory_leak Fix For: 5.1.3.CR1, 5.1.3.FINAL From an email from Bela: {quote} OK, when running async DIST with 2 nodes and numOwners == 2, I found a huge memory leak in the L1ManagerImpl ! With L1 enabled, my test with 1 passive and 1 active node wouldn't complete with 10 threads each putting 100'000 elements in the cache; instead the passive node would always OOME ! With L1 disabled, it would complete, with 23'000 TXs / sec ! Profiling the passive node (the one which would receive the modifications via RPCs), I can see that L1ManageImpl.addRequestor() leaks entries in the 'requestors' hashmap. ****** The weird thing is that L1 shouldn't even matter in the 2 node case ! ****** {quote}
