It's pretty much impossible to crash the JVM intentionally just using Java code. You have to go JNI to do that. I would (as always) be suspicious of the physical hardware. Try taking one of the servers out of service and run a memory/cpu test on it. I'll bet it's got bad memory. You didn't give any details of the crash. I'm guessing SIG11? - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkoIrc4ACgkQ9CaO5/Lv0PACWwCgvXa0DmHKjZMmIQyuWB93hyNk CnIAn2l1cvk0QihaxuguOmC9+LV5b5Wy =pKjQ -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
