Re: Tomcat freeze after some times
Yes ... in theory. But if was this case, in the jstack dump, we should view the incoming http-req which waiting for a pooled connection (I have a ConnPool.getConnection() class/method).

Hi Cris, thanks for your reply. Yes: I checked the process via top/netstat/lsof and I haven't detect any strange situation. The super-strange thing is that the other webapps, on the same tomcat-instance, continue to work when the single-app fail.

Your thread dump looks clean. Are you sure Tomcat is doing anything? If you run 'top' does it consume any CPU time? (deadlock won't consume any CPU time, but it's a good piece of information to have). - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFG1sqk9CaO5/Lv0PARAslpAJ9A1NSSmhnMKfVBrLPr4LRDv1wcYACeP4Fz J0fTXHX494UK0f3ZwRAfyMM= =079m -END PGP SIGNATURE- - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- View this message in context: http://www.nabble.com/Tomcat-freeze-after-some-times-tf4353175.html#a12421410 Sent from the Tomcat - User mailing list archive at Nabble.com. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Tomcat freeze after some times
Hi, I'm using tomcat 5.5.20 on a linux-FC7 (krn 2.6.20). Every about 20 days tomcat freeze and I must restart it. When tomcat freeze it doesn't accept any new connection (infinite connection wait) and use no CPU. As viewable form the jstack JVM dump (obtained from a freezed tomcat) it seem that tomcat have nothing to do (and .. do nothing! :( ). I have tried to freeze the client TCP/IP connections (via iptables rules), and in the Jstack-trace I see, on some threads, the calls on my classes methods.
