Add "-XX:+HeapDumpOnOutOfMemoryError" to your CATALINA_OPTS environment variable before you launch Tomcat and you'll get a heap dump file when OOME occurs. You could also enable verbose gc if you want to go back and graph the memory usage.. but if you're using javamelody you probably already have that. Once you have the heap dump, look for either single objects that are taking a huge amount of memory or one particular class that has a lot of objects and/or takes up a lot of memory per object. Follow those objects to their GC roots and you'll find out where the references are. Perhaps you have a memory leak entirely by accident, or maybe a cache that isn't tuned properly for your heap size. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk+im5MACgkQ9CaO5/Lv0PD7uQCgiKEtK56xU+l6kw/0UmxruLBf 95MAnRJ3hfZd/POoD09B12MglevNqekk =tzaU -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
