JAVAC Leaking Memory
Hi All,
I have seen in Tomcat 5.0.25 Release notes the JAVAC Leaking memory problem is mentioned. Earlier I was using Tomcat 3.3.1 and was getting java.lang.OutOfMemory Exceptions after every 2-3 days and had to restart my Tomcat Server.I am planning to migrate to Tomcat 5.0.25 version , but here too seems is the same problem .I am using jdk 1.3.1 version. If I use jdk 1.4 version,would this problem be resolved? Or is there any way to get around this problem ..?
Any feedback is welcome...
Thanks in Advance,
javaonlyjava.

WOuld be usefull to have the option to set those parameters per TC
installation, and not just per context.
If I use those switches at the web.xml of TC_HOME/conf/web.xml it will
work as it was configured at each context?

hi,
I think I am correct when I say javac is only used by tomcat compile
jsp. You should be able to eliminate javac calls by pre-compiling your
jsp pages.
Now, as I have not yet started using tc v.5.x I am not sure if this will
help, but in 4.1.x there is a switch in /tomcat/conf/web.xml to set the
jsp compiler engine to forc the process. I recomend that you check that
one out.
In my opinion, if you are using tomcat in production environment you
should turn of any "reloading-options" as they will always collect
memory. that means context reloading, auto-deployment, jsp reloading and
developement switches.
By doing that you will minimize the overhead (both process and memory)
of tomcat, leaving only the basic footprint of tomcat with the current
configuration.
Hope it helps
