Chris, I have following understanding with regards to your trailing mail comments ,pls do correct me if that's not correct :- In workers.properties (Apache end) we have directive called "connection_pool_size" which is number of those connection that each apache web server child process can made to the backend (Tomcat).So does that mean i should keep this "connection_pool_size" value in sync with threads configured for a given connector (http) in server.xml (Tomcat) in order to avoid thread exhaustion limit Is there recommendation you have with respect to Apache-Tomcat communication , that people like me ( naive) should keep in mind in order to avoid any connection time out/thread exhaustion/ response time out erorrs ?? thanks for your help as usual, Vicky

You'll need those values to be the same (yet different: read the documentation carefully) whether you are load-balancing or not. > As far as Tomcat hanging, my apologies, I discovered late yesterday > that it was Apache reaching its MaxClients limit and therefore > Apache was my bottleneck.

If you are using a load-balancer just remember that Tomcat needs to be able to handle N * M connections where N is the number of front-end servers you have and M is the number of AJP connections configured from each front-end server (which might just be the same as MaxClients). - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org/ Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iEYEARECAAYFAlCH8WEACgkQ9CaO5/Lv0PBvUgCeLRbhkrr6ZG20/rQ2w6jfCbGh yRYAn0zhKeazO+ZCdlwVb4dMFbvBgXgU =fqFb -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
