[jira] Created: (DIRMINA-49) MINA doesn't cleanup failed sockets
MINA doesn't cleanup failed sockets
-----------------------------------
Key: DIRMINA-49
URL: http://issues.apache.org/jira/browse/DIRMINA-49
Project: Directory MINA
Type: Bug
Versions: 0.7.1
Environment: A computer try to connect to an unavaible TCP port, and retry every seconds simply using :
session = connector.connect(new InetSocketAddress(hostname, port),protocolProvider);
after some times this exception is fired :
java.io.IOException: Too many open files

at org.apache.mina.io.socket.SocketAcceptor$Worker.processSessions(SocketAcceptor.java:282)
at org.apache.mina.io.socket.SocketAcceptor$Worker.run(SocketAcceptor.java:233)
Reporter: Julien Vermillard
Assigned to: Trustin Lee
Priority: Critical
(09:56:19) vrm: ran in a strange exception :
(09:56:20) vrm: 1 juin 2005 09:53:56 org.apache.mina.common.DefaultExceptionMonitor exceptionCaught
ATTENTION: Unexpected exception.

(09:56:46) trustin: Too many open files..
(09:57:13) vrm: yep I try to connect to some devices who are offlines
(09:57:20) vrm: and I retry every 2 seconds
(09:57:46) trustin: devices offline? Could you explain it more?
(09:58:43) vrm: my server try to connect to another computer (SockectConnector), but the computer is down
(09:59:15) vrm: session = connector.connect(new InetSocketAddress(hostname, port),protocolProvider);
(09:59:26) vrm: it throw an IOException
(09:59:31) vrm: (of course)
(09:59:47) vrm: and my program try to reconnect 2 seconds later
(09:59:57) trustin: Ahhhhh I see.
(10:00:08) trustin: It seems like the it doesn't clean up failed socket.
(10:00:15) trustin: Could you post it to JIRA?
(10:00:28) trustin: I'll try to fix it tonight or tomorrow morning.
(10:00:37) vrm: you know where I can see if it's cleaned or not ? (it's perhaps in my code)
(10:01:18) vrm: before I post a nobug in jira :)
(10:01:52) trustin: You can't see its cleaned or not from outside of MINA.
(10:02:36) vrm: ok
(10:02:41) vrm: I post it

[jira] Updated: (DIRMINA-49) MINA doesn't close unused selectors
Posted by "Trustin Lee (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/DIRMINA-49?page=all ]
Trustin Lee updated DIRMINA-49:
-------------------------------
Summary: MINA doesn't close unused selectors (was: MINA doesn't cleanup failed sockets)
Fix Version: 0.7.2
Failed connection attempt doesn't seem to cause FD leak, but I forgot to close unused Selectors in SessionManager implementations. So this issue is still valid. Julien, Thanks for your report!
