Dear All, we have jboss 4 installed on our server. We are using persistent mySQL as queue storage. Recently we have noticed on a consistent load of 10-12 msg/sec the dequeue process starts slowing down (we use OnMessage Event)
Initially the messages are de-queue at around 50msg/sec however as the time passes, the speed slow to 1 messages per 10 second! finally the dequeue process stop completely. The other thing we noticed that the CPU usage of java process becomes more than 97% and keep on that for hours before crashing down. We are not doing many thing in OnMessage trigger. We have also noticed that the issues was non-existence for over 1 year or so. The only recent change has been related to load increased by 10-20% (which is now again decreased to -20%). We are running jboss on fedora core 1, Celeron 2.4 Ghz processor and 1gb of RAM. Java is running with 128min and 512MB max RAM. We have also noticed that java process never uses more than 233MB of RAM. Other than jboss we have MySQL 4.1 installed on the same machine. MySQL never take more than 5% of CPU with 33MB of RAM. regards Shantanu Chauhan shantanuDOTsinghATvfirstDOTcom View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3987783#3987783 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3987783 _______________________________________________ jboss-user mailing list [email protected] https://lists.jboss.org/mailman/listinfo/jboss-user
