What does SIZE report when your CPU goes to 100%? Your CPU going to 100% makes /much/ more sense than "memory at 100%" or whatever you were trying to say earlier. If your CPU goes to 100%, you should take a thread dump of the JVM and see what threads are working so hard. Usually, more than a fraction of a second at 100% CPU means that some code is in an infinite loop and probably doing nothing useful. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkfpJkoACgkQ9CaO5/Lv0PBexACeJkXi4IU+x1C+MiicT+lcVdHr oRwAn0Cv+JK26ERUNJzt5+8V1pqNVi65 =KA0p -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
