Looks like you have Tomcat listening on a private interface to port 8009 (which is the default AJP/1.3 port) and another process on the local machine is connected to it (most likely Apache httpd). Did you know that AJP connections are intended to be (and, in a default configuration, are) persistent? That means that if you forward 10 connections from httpd -> Tomcat, you will likely have 10 connections maintained between httpd -> Tomcat for a while -- a few minutes probably. All of this you can configure: just read the documentation for mod_jk and the AJP connectors (remember: there are 3 of them: BIO, NIO, and APR). > Yes, i have observed this behavior after installing nagios. Did you notice different behavior before? Or are you only now noticing that AJP connections are long-lived? - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEAREIAAYFAlE20t8ACgkQ9CaO5/Lv0PCUFQCePm1hhg3mCWbGkJGG+9lEABfK ta0AnjgdEAzvm4DTDumQu7ydHlAY5Qwp =aF7y -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
