lviz Feb 1, 2005 7:13 AM (in response to knutschik)hi again
afaik there where some memory leaks reported in 3.2.3
can't remember exactly (i thought they had todo with redeployment..)
anyway..
have you ever tried to upgrade the jboss-version ?
just to get it clear if it is jboss and not the solaris java version.
btw:
which java 1.4.2_??
cheers

knutschik Feb 1, 2005 7:24 AM (in response to knutschik)java-version: 1.4.2_03-b02
I cannot change the JBoss-Version, because we use it in production area.
Where can I find something about performance leaks and how to solve the problems?
Solaris cannot be the reason, because there are no problems with the other servers. -

lviz Feb 1, 2005 8:31 AM (in response to knutschik)hello
tuning java for performance..
http://java.sun.com/docs/performance/
i did not mean solaris is the reason ;)
(the java version for solaris could be a reason)
did the performance/memory leaks appear from beginning ?
i can remember something about damaged jars, ears,.. and problems with
scanner thread.
is this the only instance of jboss on your machine?
maybe you would like to install a second(newer) jboss instance on you machine for testing.
i know how hard it can be to track down such things..
(we use jboss in a cluster with load balancing.. blabla...)

knutschik Feb 1, 2005 10:02 AM (in response to knutschik)No, we have serveral server-instances on the server, but the problem appears only in one server.
One server configuration is equal to the problem-server and there are no problems.
It's very curios because in the server is no application deployed and the cpu and memory usage is highly increasing. -

lviz Feb 1, 2005 10:29 AM (in response to knutschik)phew !;
if i had that info about several instance of jboss on one machine running fine
and just one going crazy in your first post... ;)
did you try to shut down the bad (empty) instance (make a backup, delete the files) and copy the working (equal) instance over the bad one (you have to change the ports!) and start again ?
cheers
