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.

If you want to work with me, we can make that happen, assuming you have a way to reproduce this Filip Matías Rojas wrote: > 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 > > > --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
