I don't really have an answer for you, but Google'ing "iis 10 connection limit" returns a lot of hits. It looks like a fairly common question/issue. Maybe it'll help.

I've been trying to track down a problem whereby all of the web apps under our Tomcat instance are seeming to stall. There's no indication of any problems in the Tomcat logs themselves. I suspect IIS is unable to forward requests to Tomcat. I either have to recycle the IIS worker process or restart Tomcat to resolve the problem. Here's what I'm seeing with netstat (port 8008 is my AJP 1.3 port): Z:\>netstat -a -n | grep 8008 TCP 0.0.0.0:8008 0.0.0.0:0 LISTENING TCP 147.92.2.137:2871 147.92.2.137:8008 ESTABLISHED TCP 147.92.2.137:2915 147.92.2.137:8008 ESTABLISHED TCP 147.92.2.137:2944 147.92.2.137:8008 ESTABLISHED TCP 147.92.2.137:2965 147.92.2.137:8008 ESTABLISHED TCP 147.92.2.137:2969 147.92.2.137:8008 ESTABLISHED TCP 147.92.2.137:3019 147.92.2.137:8008 ESTABLISHED TCP 147.92.2.137:3034 147.92.2.137:8008 ESTABLISHED TCP 147.92.2.137:3039 147.92.2.137:8008 ESTABLISHED TCP 147.92.2.137:3041 147.92.2.137:8008 ESTABLISHED TCP 147.92.2.137:3060 147.92.2.137:8008 ESTABLISHED TCP 147.92.2.137:8008 147.92.2.137:2871 ESTABLISHED TCP 147.92.2.137:8008 147.92.2.137:2915 ESTABLISHED TCP 147.92.2.137:8008 147.92.2.137:2944 ESTABLISHED TCP 147.92.2.137:8008 147.92.2.137:2965 ESTABLISHED TCP 147.92.2.137:8008 147.92.2.137:2969 ESTABLISHED TCP 147.92.2.137:8008 147.92.2.137:3019 ESTABLISHED TCP 147.92.2.137:8008 147.92.2.137:3034 ESTABLISHED TCP 147.92.2.137:8008 147.92.2.137:3039 ESTABLISHED TCP 147.92.2.137:8008 147.92.2.137:3041 ESTABLISHED TCP 147.92.2.137:8008 147.92.2.137:3060 ESTABLISHED Every time the stall has happened, I have noticed that there are always exactly ten connetions between IIS and Tomcat (they're on the same server). Everything works fine until we reach this point. In my JK log, I'm seeing things like this: [Wed Aug 24 14:10:57 2005] [error] ajp_connection_tcp_get_message::jk_ajp_common.c (961): Can't receive the response message from tomcat, network problems or tomcat is down (147.92.2.137:8008), err=-54 [Wed Aug 24 14:10:57 2005] [error] ajp_get_reply::jk_ajp_common.c (1503): Tomcat is down or refused connection. No response has been sent to the client (yet) My workers.properties looks like this: worker.list=ajp13a worker.ajp13a.port=8008 worker.ajp13a.host=www.bvu.edu worker.ajp13a.type=ajp13 cachesize=20 cache_timeout=600 recycle_timeout=300 And here's the AJP connection defininition from my server.xml: <Connector port="8008" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="443" debug="5" connectionTimeout="20000" protocol="AJP/1.3"/> Any idea what might be happening? It sure looks like I'm hitting some kind of 10 connection limit somewhere, but I can't seem to figure out where. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
