Can it be that a JBoss instance will launch other JBoss instances?
We observed JBoss duplicate processes on our system running JBoss 4.2.0.GA on Sun T5220
machines with Solaris 10.
After we run JBoss for several hours we sometime see several JBoss processes running
instead of only one, although we launch only one JBoss instance (we made sure by adding
logging to the JBoss run.sh launch script). Also the new duplicate JBoss processes have
the parent pid of the original JBoss process (the original JBoss process has a parent pid
of it's run.sh process). The JBoss processes have the same parameters as the original
JBoss process and take the same amount of memory.
Here's an example of running the ps -ef | grep run.sh command:
anauser 16082 1 0 12:45:50 ? 0:00 /bin/sh
/export/home/ana41/jboss/bin/run.sh -b 0.0.0.0
anauser 16093 16082 2 12:45:50 ? 960:40 /export/home/ana41/java/bin/java
-Dprogram.name=run.sh -server -Xms2048m -Xmx20
anauser 5623 16093 0 00:48:39 ? 0:00 /export/home/ana41/java/bin/java
-Dprogram.name=run.sh -server -Xms2048m -Xmx20
anauser 5627 16093 0 00:48:43 ? 0:00 /export/home/ana41/java/bin/java
-Dprogram.name=run.sh -server -Xms2048m -Xmx20
anauser 5590 16093 0 00:48:31 ? 0:00 /export/home/ana41/java/bin/java
-Dprogram.name=run.sh -server -Xms2048m -Xmx20
We also see that the Total Running time of these duplicate processes are almost always 0.
We saw only once a duplicate JBoss process with a running time of 2, and then that process
disappeared. I have a theory that maybe these Processes are stuck because their output
stream are not read or directed to anywhere. We still have no idea what launched these
processes.
Will appreciate any advise.
Thanks,
Ido
