we have a nasty problem with our application which runs in a JBoss/Tomcat ApplicationServer.
after a while (sporadicaly) JBoss does not response, or is very slow, for every client.
If i look after the system (linux RedHat 6.2) one of the java-processes take 100% of CPU.
It is the third process in the list (e.g):
1108 1 ==> started java -server -D. . .
1152 1151 ==> this is the process with 100%
115? 1151 more than 80 processes . .
If this problem occurs I can't stop the server 1108 with SIGHUP.
Only if I do a kill -9 1152 after, the server shut down.
Server runs on Linux RedHat 6.2 / javaVM StandardEdition HotSpot 1.3.1-b24 JBoss-2.2.2_Tomcat-3.2.2
Our application : EJB 15*CMP-Entity 20*Session 1*StatefulSession and a couple of JSP-pages
anyone with any idea ?
