[infinispan-issues] [JBoss JIRA] (ISPN-9512) *TxPartitionAndMerge*Test tests hang during teardown

*TxPartitionAndMerge*Test tests hang during teardown ---------------------------------------------------- Key: ISPN-9512 URL: https://issues.jboss.org/browse/ISPN-9512 Project: Infinispan Issue Type: Bug Components: Test Suite - Core Reporter: Dan Berindei Assignee: Dan Berindei Labels: testsuite_stability Fix For: 9.4.0.CR3 Attachments: master_20180913-1119_PessimisticTxPartitionAndMergeDuringRollbackTest-infinispan-core.log.gz, threaddump-org_infinispan_partitionhandling_PessimisticTxPartitionAndMergeDuringRollbackTest_clearContent-2018-09-13-13828.log Not sure what changed recently, but the thread dumps show a state transfer executor thread blocked waiting for a clustered listeners response. The stack includes two instances of {{ThreadPoolExecutor$CallerRunsPolicy.rejectedExecution()}}, which suggests that at some point all the state transfer executor threads (6) and async transport threads (4) were busy, and the transport thread pool queue (10) was also full. {noformat} "stateTransferExecutor-thread-PessimisticTxPartitionAndMergeDuringRollbackTest-NodeC-p57758-t1" #192601 daemon prio=5 os_prio=0 tid=0x00007f7094031800 nid=0x5b27 waiting on condition [0x00007f70190ce000] java.lang.Thread.State: TIMED_WAITING (parking) at sun.misc.Unsafe.park(Native Method) -
