[jira] [Created] (IGNITE-1386) IPC semaphores are not released on server endpoint abrupt stop

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

             Summary: IPC semaphores are not released on server endpoint abrupt stop
                 Key: IGNITE-1386
                 URL: https://issues.apache.org/jira/browse/IGNITE-1386
             Project: Ignite
          Issue Type: Bug
          Components: general
            Reporter: Denis Magda
            Priority: Critical
             Fix For: ignite-1.5


{{IpcSharedMemoryCrashDetectionSelfTest.testIgfsClientServerInteractionsUponServerKilling}} stops a server endpoint abruptly with 'kill' command and right after that start a new endpoint.

The test expects that such a flow will release all previously allocated memory segments and semaphores.

In fact, only memory segments are released while semaphores stay in the system. However, the test successfully ends.

Steps to reproduce:
- check existing semaphores with {{ipcs -s}};
- start the test on Linux or Mac OS;
- call {{ipcs -s}} and you will see that semaphores hasn't been released.

In addition, TeamCity agents fail a test suite because of this reason from time to time
