Do you have physical access? If it's x86 and you do have physical access, 100% you should run memtest86+ against it. Let it run all night. If it's a production server, replace it with one you trust and then figure out what the problem is with the old box. We had 6 app servers at [bloated CA name removed to protect the guilty] in production and 2 of them were giving us SIG11's. The solution was to throw them out and replace them with 2 new ones. One of those sucked, too, so we had to play server-roulette again before we got all 6 good ones. Good luck, - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkmMg2sACgkQ9CaO5/Lv0PACwACgmYPdCqQLUoBxnJGtT/CLrsSQ M5AAnRjFYbOp6xqfFj1/mc4/Qn/G/7to =tvDm -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@tomcat.apache.org For additional commands, e-mail: users-help@tomcat.apache.org
