---------------------------------------

             Summary: "long running transaction/cache operations" during load tests
                 Key: IGNITE-3619
                 URL: https://issues.apache.org/jira/browse/IGNITE-3619
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 1.6
            Reporter: Ksenia Rybakova


The following warnings appear during load test:
{noformat}
[15:46:07,413][WARN ][grid-timeout-worker-#79%null%][GridCachePartitionExchangeManager] Found
long running transaction [startTime=15:45:04.471, curTime=15:46:07.356, tx=GridNearTxLocal
[mappings=IgniteTxMappingsImpl [], nearLocallyMapped
...
[15:46:07,787][WARN ][grid-timeout-worker-#79%null%][GridCachePartitionExchangeManager] Found
long running cache future [startTime=15:45:04.775, curTime=15:46:07.356, fut=GridNearTxFinishFuture
[futId=905d64b4651-3154c7e5-c2bd-46d5-a2ae-
...
[15:46:07,830][WARN ][grid-timeout-worker-#79%null%][GridCachePartitionExchangeManager] Found
long running cache operations, dump threads.
[15:46:07,831][WARN ][grid-timeout-worker-#79%null%][GridCachePartitionExchangeManager] No
deadlocked threads detected.
{noformat}

In some cases these warnings appear during preloading, in other cases during performing main
test.
In all cases CPU at part of the nodes drops almost to 0% and test hung.
