Well I run in exactly the same environment except it's a RedHat 6.2
(-ish) box
My server.xml is setup like so:
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector className="org.apache.ajp.tomcat4.Ajp13Connector"
port="8009" minProcessors="3" maxProcessors="15"
acceptCount="10" debug="0"/>
The connector is setup like so:
# BEGIN workers.properties
worker.list=ajp13
worker.ajp13.port=8009
# change this line to match apache ServerName and Host name in
server.xml
worker.ajp13.host=www.whatever.com
worker.ajp13.type=ajp13
# END workers.properties
HTH.
I can't see anything in your setup which instantly looks wrong but there
appear to be some parameters which are unnessecary, although I'm not
sure. Could it be anything to do with your timeout set to 0?
Apart from that it looks like it could be something on the SQL side
that's causing the problem.
IMHO, have a glance at the sql server logs.
