Tomcat IIS Isapi error

I am using the AJP13 Connector to map requests from IIS, acting as front end web server, to Tomcat as my middle ware. This was working fine for a long time with only minor problems, but recently, the failure rate has increased dramatically that 25% of the transactions are failing.

I have taken a look at the Isapi log, and this is what I got:

[Wed Jun 14 14:09:46 2006] [info] ajp_service::jk_ajp_common.c (1665): Sending request to tomcat failed, recoverable operation attempt=0
[Wed Jun 14 14:12:00 2006] [error] ajp_connection_tcp_get_message::jk_ajp_common.c (933): ERROR: can't receive the response message from tomcat, network problems or tomcat is down (, err=-1
[Wed Jun 14 14:12:00 2006] [error] ajp_get_reply::jk_ajp_common.c (1432): Tomcat is down or network problems. No response has been sent to the client (yet)
[Wed Jun 14 14:12:00 2006] [info] ajp_service::jk_ajp_common.c (1645): Receiving from tomcat failed, recoverable operation attempt=0
[Wed Jun 14 14:12:00 2006] [info] ajp_service::jk_ajp_common.c (1665): Sending request to tomcat failed, recoverable operation attempt=0

I have a log full of these messages now, and as the error suggests either Tomcat is down or its a network problem. Tomcat is up, and we tried restarting it. Also, we did a ping between IIS and Tomcat for continuous 24 hours without any problems. So, there is no network problem it seems.

I have even gone further and disabled TomcatAuthentication! So now, we are real stuck and in a very bad shape. Its extremely important to get it fixed soon.

Anyone with any hints, please dont hesitate to help.

There aren't many rules that you need to worry about here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.
