9:07 a.m.
I'm trying out JBossAS 4.3.0 GA CP03. I've discovered that I run out of
deployment descriptors when redeploying things in the container. I've tested this out
on a base installation of EAP. I deployed a single ear in the container. The ear
contains some MDB's. I then used the following to redeploy the ear every 6 seconds up
to 1000 times:
for i in `seq 1 1000`; do touch /var/lib/jbossas/server/production/deploy/MY-EAR.ear;
sleep 6; echo "lsof count ($i) = `ps aux | grep "^jboss" | grep Main | sed
's/^[^ ]*\s*\([^ ]*\).*/lsof -p \1 | wc -l/g' | sh`"; done
This redeploys the ear, waits 6 seconds, then prints the line count from lsof for the
jboss process along with the redeployment count. In my most test I run out of file
descriptors after 315 redeployments. I've seen it fail a lot more. If I add in the
full complement of stuff normally deployed for my scenario I see failure after as few as 7
redeployments.
Checking the lsof count (lsof -p 9999 | wc -l) shows the count goes up for a while, then
drops down. This drop occurs roughly every 50 redeploys, but never drops down
completely.
Here is my original post:
http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4199195
Looking at lsof changes over time, it looks like the container is keeping a handle on the
jar files contained within the ear, even after the ear is undeployed completely.
Any idea why this is happening? I'm currently using JBossAS 4.3.0 GA CP01 and have
never seen this problem in that version nor any previous versions. Note that I was unable
to use CP02 due to some bugs that have been fixed in CP03.
Here is the exception I got in my initial testing, as noted on the linked post:
