Projects tigase _server server-core Issues #1069
BindException: Address already in use (#1069)
wojciech.kapcia@tigase.net opened 5 years ago

Recently it happens quite often on our installation, that Tigase fails to start listening on 5223 with following exception:

[2019-08-31 01:41:38:000] [FINE    ] [scheduler_pool-14-thread-1-c2s ] ConnectionManager.startService(): Starting service: {remote-host=localhost, port-no=5223, new-connections-throttling=50, ifc=[Ljava.lang.String;@7f80baec, socket=ssl, type=accept}
[2019-08-31 01:41:38:001] [WARNING ] [  ConnectionOpenThread ] ConnectionOpenThread.addAllWaiting(): Error: creating connection for: {remote-host=localhost, port-no=5223, new-connections-throttling=50, ifc=[Ljava.lang.String;@7f80baec, socket=ssl, type=accept}

What's problematic/weird in this case, is that seems like a second call to start the service - there is already one before roughly 1 minute earlier:

[2019-08-31 01:40:42:496] [FINE    ] [       pool-1-thread-8 ] ConnectionManager.startService() : Starting service: {remote-host=localhost, port-no=5223, new-connections-throttling=50, ifc=[Ljava.lang.String;@7f80baec, socket=ssl, type=accept}

Same double entry happens for 5222, but it starts OK.

[2019-08-31 01:40:42:496] [FINE    ] [       pool-1-thread-8 ] ConnectionManager.startService() : Starting service: {remote-host=localhost, port-no=5222, new-connections-throttling=200, ifc=[Ljava.lang.String;@7f80baec, socket=plain, type=accept}
…
[2019-08-31 01:41:38:000] [FINE    ] [scheduler_pool-14-thread-1-c2s ] ConnectionManager.startService(): Starting service: {remote-host=localhost, port-no=5222, new-connections-throttling=200, ifc=[Ljava.lang.String;@7f80baec, socket=plain, type=accept}

I'm completely sure there is nothing listening on that port before starting Tigase:

kotali@ip-10-0-36-197:~$ sudo lsof -iTCP:5223 -sTCP:LISTEN -Pn | wc -l

I've found an issue (possible race condition) in code responsible for port binding (connection manager initialization). I've fixed this issue and this should fix startup issue.
Andrzej Wójcik (Tigase) commented 5 years ago

I'm reassigning back to me as the fix is not working in all cases.
Andrzej Wójcik (Tigase) commented 5 years ago

Now the issue is (I think so and hope so) fixed.
