Galder Zamarreño commented on ISPN-4579:
----------------------------------------

@dan, we can possibly set SingleNodeJdbcStoreIT to be unstable? While https://github.com/infinispan/infinispan/pull/2774 gets completed to get TRACE more easily for server, TRACE can already be obtained selective using the method in https://github.com/infinispan/infinispan/tree/master/server/integration/testsuite by passing in -Dlog.level.infinispan=TRACE. I'm not sure, but the log file might be rotating one though. WDYT?

> After a failure in {{SingleNodeJdbcStoreIT.testForcedShutdown}}, it seems not all the test stores are properly initialized, and cleanup fails with a NullPointerException:

> {noformat}
> This bug is only about the NPE, the test failure is agent-specific (probably caused by the low open files/user processes limits).
