Hello,
I have an application running under Tomcat for a couple of months
now, and itś always been memory intensive (I run it in a combination
with Apache2 + JK + Berkeley DB XML in the backend). But from a few
days to today, it's been eating memory like crazy, and I can see that
when I have to restart it very often - 170 Tomcat instances running!
The site running is not that traffic intensive, so my first
supposition is that something is getting locked and making Tomcat
unable to release the memory when the job is done. So instances get
created but not destroyed. And memory progressively is filled, up to
50% of swap, then Apache2 stops responding, BDB XML gives
out-of-memory messages etc... which is pretty normal.
My question is if this is related to Tomcat directly - like a
memory leak, or if this is application / database specific. How could
I investigate this further? My setup:
Debian Linux 2.6.18-5-686 #1 SMP
Apache 2.0.54
Tomcat 5.5.15
JDK 1.5.0_06-b05
BDB XML 2.2.13
1.5 GB of RAM
regards,
