1. Re: Help! JBoss in Production Environment suddenly shutdown
adrian.brock Mar 12, 2003 11:49 PM (in response to joeho)Do you mean a clean shutdown or a crash?
If it is a crash it is likely an out of memory
or some other out of resources problem that the jvm is
not handling cleanly.

2. Re: Help! JBoss in Production Environment suddenly shutdown
joeho Mar 13, 2003 11:32 AM (in response to joeho)Thanks Adrian, I think it is a crash since it 'disappear' suddenly. I have received many customer complain.
My current JVM optioon setting is '-Xincgc -Xms512m -Xmx1500m' and my machine has 2GB RAM. I have tried to increase -Xmx to more than 1500m but JBOSS does not start at all. What can I tune (JBOSS config. / tomcat)??
Thanks a lot. -

adrian.brock Mar 16, 2003 7:58 PM (in response to joeho)The two major controls for memory are
the entity bean cache size set in standardjboss.xml
(default 1 million) and the jms cache max memory which
won't set in jbossmq-service.xml
A more likely problem is the number of file descriptors
controlled by ulimit. This is includes open sockets.
Consider an alternate JVM which might give more
informative information rather than just crashing.

bcaceres-tririga Mar 17, 2003 12:22 PM (in response to joeho)If you are using UNIX, are you starting the jboss
process using "nohup". This may be a silly question,
but I've seen it before where the shell in which
the process was started exists and the background
process dies because "nohup" wasn't used. -

joeho Mar 18, 2003 11:52 AM (in response to joeho)Thanks, bcaceres-tririga. I am using Linux and I just use the bundled startup shell script to start Jboss. Still cannot find the reason....
