Look for heap activity that looks like this: /\/\/\/\/\/\ ~ __/ ~ ___/ ~ ___/ When you start seeing this: __/ You have a problem! Just because your threads are not being used too much doesn't mean there aren't other problems lurking. Even with low thread utilization, a bad heap graph can mean that you're just waiting around for an OOME. Consider performing load tests and watching the numbers instead of just watching a typical hour of a typical day. You need to plan for peak load, not for average load. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkfQIYoACgkQ9CaO5/Lv0PAcQwCfcXMtpU3JklRx074q8y2d1cn5 6mAAoLiPX9LMAAOjk31uAiQRFu1Uot+q =Yfxr -----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]
