9:10 a.m.
I have been experiencing constant 'Too many open files' exceptions on the
TaskClient during connect()
For every operation, I connect and disconnect as such…
TaskClient client = new TaskClient(new MinaTaskClientConnector("client 1", new
MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));
…. invoke operation on the task server (complete, release, claim, …)
client.disconnect();
The exception only manifests itself when attempting to connect to the task client, the
remaining of the application (database connections, servlet requests, …) complete
successfully.
Any insight on this would be very much appreciated.
Thank you.

Yes, I saw that problem in a linux machine only. It's about the amount
sockets that the system is able to open.
I remember looking at the Mina documentation to see how to fix it, but
something should be wrong there.. because it's not supposed to open a huge
amount of sockets for working.

Mauricio,
thank you for the really fast response on this…
after your suggestion, I came across this …
http://mina.apache.org/faq.html#FAQ-Myserverfailswithjava.net.SocketExcep...
but it appears that the connections on my system are not being closed at all, not sure why
they aren't timing out.
Unless I shutdown Tomcat and restart it, the file handlers do not get released.
I could change my limit to something else, but I feel this would just delay the problem by
a few seconds or minutes at the best.
Any other suggestions?
regards,

I'm not sure about that..
Can you try increasing that number?. That's the exact wiki that I've saw.
and increasing from 1000 to 1500 stop showing that problems. Probably is a
problem related with the time that is taking to close the sockets.
cheers

Mauricio,
I will give this a shot and see if it resolves the problem.
I am both upping the ulimit and changing the timeout to try and resolve it…. fingers
crossed.
thanks

I'm not sure about that..
Can you try increasing that number?. That's the exact wiki that I've saw. and
increasing from 1000 to 1500 stop showing that problems. Probably is a problem related
with the time that is taking to close the sockets.
cheers

Mauricio,
thank you for the really fast response on this…
after your suggestion, I came across this …
http://mina.apache.org/faq.html#FAQ-Myserverfailswithjava.net.SocketExcep...
but it appears that the connections on my system are not being closed at all, not sure why
they aren't timing out.
Unless I shutdown Tomcat and restart it, the file handlers do not get released.
I could change my limit to something else, but I feel this would just delay the problem by
a few seconds or minutes at the best.
Any other suggestions?
regards,

Yes, I saw that problem in a linux machine only. It's about the amount sockets that
the system is able to open.
I remember looking at the Mina documentation to see how to fix it, but something should be
wrong there.. because it's not supposed to open a huge amount of sockets for working.
Cheers

I have been experiencing constant 'Too many open files' exceptions on the
TaskClient during connect()
For every operation, I connect and disconnect as such…
TaskClient client = new TaskClient(new MinaTaskClientConnector("client 1", new
MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));
…. invoke operation on the task server (complete, release, claim, …)
client.disconnect();
The exception only manifests itself when attempting to connect to the task client, the
remaining of the application (database connections, servlet requests, …) complete
successfully.
Any insight on this would be very much appreciated.
Thank you.
