Tomcat itself is extremely stable. This is most likely an application problem. Perhaps your application does well with little traffic but does not scale well. You got a burst of traffic and everything fell apart. ?? > How could > I investigate this further?

If you are getting OOMEs, then you need to find out what's causing you to run out of memory. Several memory profilers are mentioned on this list all the time. It's also not a bad idea to have the JVM record a thread dump to stdout whenever an OOME occurs. You can find all of this information in the list archives or google. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHVFv69CaO5/Lv0PARAusIAKCsGGlEintDCawwXQygze3mpqmLdwCgjsYC 5DYtYAd92gr6nJ5DREoKJvI= =88yd -----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]
