Tomcat startup errors

[msb21]

I emerged tomcat and am unable to start. I checked in catalina.log and here is the output.

I'm having a very similar error though its on a totally different version of Tomcat and quite some time has passed. Did you ever end up solving this problem?

My catalina.out file looks like this:

Tomcat outOfMemory errors are horrible. I've been dealing with them on and off for ages, and I'm not much closer to understanding them.

The JVM has memory limits, though, which you can set. By default the memory limit for a jvm is quite small.
To tweak them, edit /etc/conf.d/tomcat, and set something like CATALINA_OPTS="-Xmx512M -Xss256k -server -Xms140M"
Don't just use those values - look in man java for explanations of -Xmx, -Xss and -Xms, then see whether tweaking them works for you. The settings we use kind of work, but context restarts are a killer - better to restart the whole of tomcat. Also, top shows a huge memory usage for java more or less all the time, but I have a feeling it's partially spurious due to some weird kernel memory reporting anomolies. If anyone has any more experience of dealing with java/tomcat memory management on gentoo, I'd love to know.

rex123, thank you for your reply, I just figured out what I was doing wrong. I had gone through the security handbook and had limited the number of threads any given user could use.

See: https://forums.gentoo.org/viewtopic-t-326640-highlight-tomcat+memory.html

I've fixed this problem by tweaking the settings as mentioned in the article.

thank you again
