stack commented on HBASE-5995:
------------------------------
TestLogRolling.testLogRollOnPipelineRestart failed on hadoop1 here:
https://builds.apache.org/job/hbase-0.95/352/consoleText It went zombie.
In the double thread dump on the end:

... we are stuck here.
The math looks like it could go wonky. But looking in the output for the test,
it seems that when this test ran we got this:
2013-07-23 01:23:29,560 INFO [pool-1-thread-1] hbase.HBaseTestingUtility(922):
Minicluster is down
2013-07-23 01:23:29,574 INFO [pool-1-thread-1] hbase.ResourceChecker(171):

(was 31) - Thread LEAK? -, OpenFileDescriptor=312 (was 272) -
OpenFileDescriptor LEAK? -, MaxFileDescriptor=40000 (was 40000),
SystemLoadAverage=351 (was 368), ProcessCount=144 (was 142) - ProcessCount
LEAK? -, AvailableMemoryMB=906 (was 1995), ConnectionCount=0 (was 0)
So we were up against the fd limit.
