Tomcat Memory leaks!

Hi. It seems Tomcat (4.1.24) has a major memory leak, and I wanted to bring
it to the developers attention so they can check it out.

I run a shared hosting server (Mandrake 8.2, Apache 1.3) with virtual hosts.
I have 1 Gig of RAM and about 50 virtual hosts and yet I keep getting Out of
Memory errors!

I have made numerous adjustments to memory allocations, yet nothing helps.
Here's an example of what I've done:

CATALINA_OPTS="-Xmx64mb"
and
CATALINA_OPTS="-Xmx1028mb"

I can furnish my server.xml file upon request or anything else you may need
to fix the problem.

Thanks

Have a look here:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper-howto.html

In your <tomcat_home>/conf/web.xml you can modify the following like this
(assuming you have Jikes installed):

    <servlet>
        <servlet-name>jsp</servlet-name>
        <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
        <init-param>
            <param-name>logVerbosityLevel</param-name>
            <param-value>WARNING</param-value>
        </init-param>
        <init-param>
            <param-name>fork</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <param-name>compiler</param-name>
            <param-value>jikes</param-value>
        </init-param>
        <load-on-startup>3</load-on-startup>
    </servlet>

Hi. I honestly have no idea what you are talking about. Can you explain what
needs to be done for this? You talking about changing `javac`? Thanks

Try the option to fork off the JSP compiles (or even use Jikes to compile).

There seems to be a problem with compiling of JSPs that does not use the
usual memory you can allocate with the -Xmx type flag... maybe one of the
guru's can explain this.. but we had similar problem that whe nwe moved to
jikes forked compiles went away...

Hope that helps.

Cheers,
Alex.
