It is parameter parsing code. It cannot claim the request as malformed

That depends upon how you have configured your access log: you can
configure an access log to log only requests that failed and the

Unlikely. If you are using SSL or serving large static files,
APR/tcnative should be something that you look into using.
I do use SSL, but all is dynamic jsps
Honestly, I would put more effort into upgrading to a more recent
version of Tomcat than looking into using APR/tcnative.

Do you mean that Tomcat actually paused its connectors
Just the -XX:+HeapDumpOnOutOfMemoryError you already have. Tomcat
usually doesn't shut down nicely (as evidenced by the pausing of
connectors in your log file) when you get an OOME. Are you sure that

Yes, it's still running. Should i disable it?
You asked the Tomcat users' group, not the Javamelody users' group:

The author is around and some other users too, since the recommendation
of using this software actually came from this user group.
