Re: Tomcat5/mod_jk Memory Leak/mod_jk bypass
Ran out of memory last night again
Set to 512m and ran out at 284m
Maybe I am missing a paramater in the tomcat setup on windows or something
Frustrating

This particular issue has been fixed in Tomcat 5.0.x already. Please
download the latest release.
As the thread starter James mentioned, his memory leak problem was not
because of this issue as he is running the latest, 5.0.25.

I can confirm that this works with mod_jk too.
I'm a little surprised that fixing this rather horrible memory leak
doesn't appear to be a high priority. We were almost at a point of
abandoning Tomcat altogether since we couldn't keep our test environment
running for more than 2 days without OutOfMemory problems while it would
run for weeks on end with JRun3. Adding this line made all our problems
go away, and we are now well on our way to completing our migration to
Tomcat.

I was having a memory leak using mod_jk2, and it was fixed by adding
request.registerRequests=false
to tomcat/conf/jk2.properties.
I don't know if this would work with mod_jk, but it might be worth a try.

Posted by Mark Lowe <ma...@boxstuff.com>.
I have this in our startup scripts
export CATALINA_OPTS="-Djava.awt.headless=true -Xmx128m -Xdebug"
Perhaps the debug argument might reveal something. I cant be much help
on windows matters as I try not to get involved with anything like
that.
My app is still running, but linux not windows so i don't know how far
i can compare. I also have no idea about compiling jk under windows,
i've always found that I've needed to compile jk often with the head
version out of cvs (there's always a fix thats needed somewhere).
