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