Hi Filip,
Thanks for your response.
I can only reproduce it on production, where we are running a Linux 2.6
Kernel with JDK 6 update 7. After a high load it is still running at 100%
CPU usage (sometimes 200% or 300% taking 2 or 3 cores).
Today I'll try to do some profiling to detect the exact cause, but the bug I
mentioned before sound like a possible cause to me.
I understand that you said that the bug is not fixed in JDK 6 update 7?
It's strange because here
http://java.sun.com/javase/6/webnotes/ReleaseNotes.html it says that the bug
is fixed.
Thanks,
Matías

hi Matías,
I have not yet found a way to reproduce it to put in a work around so
even though its not fixed in 1.5 and 1.6, we can make it work.
If you want to work with me, we can make that happen, assuming you have
a way to reproduce this

Hello,
I'm experiencing a problem with NIO in Tomcat, maybe related to this
issue:
Selector doesn't block on Selector.select(timeout) (lnx)
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6403933
I'm using JDK 6 update 7 and it seems not to be fixed, does anybody have
the
same problem?
When in heavy load, CPU usage goes to 100% and the only way to go back to
normal is restarting Tomcat.
Thanks,
Matías
