memory leak in tomcat 5.0.16 ? 2004-01-22 - By Allistair Crossley
Back
1.4.1_03 on W2K. I have no idea what the consumption of memory should be like
but previous posts where I mentioned this about of RAM have had replies saying
it was a lot. Depends on what you app does I guess. Ours has a real large XML
nav tree in app scope that is used a lot on each request, we have a backend CMS
to get search results for thousands of docs and all their meta data gets stored
in properties files and we also do lots with the SQL server. At the moment all
that is down to 30MB as shown in JProfiler's heap used view.
What puzzles me is the Windows task manager process memory as this never ever
matches anywhere near the JProfiler reported memory. I know there may be some
system overheads but the 30MB heap that JProfiler reveals is actually 90MB in
Windows task manager.
Go figure?

Out of curiosity, which JVM do you run? I run Tomcat 5.0.18, JVM 1.4.2_03 for
Linux on Red Hat, and two instances of JSPWiki serving no more than 200 users.
This combination consumes a steady 121MB. Is this normal or excessive?

We had exactly the same problem. 2 users on 5.0.16 after 20 minutes the RAM
consumed was 158MB and then it crashed.
Upgraded to 5.0.18 yesterday and RAM is a steady 30MB.
I dont care what anyone says, 5.0.16 had a problem!

Note that the download page on Jakarta.apache.org is not updated with this new
release. You need to figure the good URL by yourself (not so hard).
