Coldfusion 9 problems - have to keep restarting service every now and then

Question

I've been having problems lately with Coldfusion 9 on Windows.
Apache logs show:
[Tue Jan 25 11:45:28 2011] [notice] jrApache[2088: 55360]  Couldn't initialize from remote server, JRun server(s) probably down.
[Tue Jan 25 11:45:28 2011] [notice] jrApache[2088: 10694]  could not initialize proxy for 127.0.0.1:51800
[Tue Jan 25 11:45:28 2011] [notice] jrApache[2088: 10694]  Couldn't initialize from remote server, JRun server(s) probably down.
[Tue Jan 25 11:45:29 2011] [notice] jrApache[2088: 54283]  could not initialize proxy for 127.0.0.1:51800
[Tue Jan 25 11:45:29 2011] [notice] jrApache[2088: 54283]  Couldn't initialize from remote server, JRun server(s) probably down.
[Tue Jan 25 11:45:30 2011] [notice] jrApache[2088: 6919]  could not initialize proxy for 127.0.0.1:51800
But Coldfusion is responsive (on port 8500).
The problem seems to get fixed if I stop both Apache, and Coldfusion, and restart them again.
CPU use and Memory use at the time of the problem are minimal (around 2% and 1GB for CF).
I believe the problem is with the Connector itself, but I have no idea how to diagnose.
It's not saturation, because at the time of the problem, around 4-5 requests are being serviced (according to cfstats)

1   5   4   196 -1  -1  0     3     0     0      -136   0      3375   0
Any ideas how to attack the problem of what other information I can provide? It's driving me nuts, since I cannot figure it out.
Thanks in advance.

No need to wait. Just find the details prior to the last crash restart. Your CF startup will have this syntax:
Starting Macromedia JRun 4.0 (Build 108858), coldfusion server
01/24 14:54:36 Information [main] - Starting Event Gateways.
01/24 14:54:36 Information [main] - Starting FlexAssembler...
01/24 14:54:36 Information [main] - Starting .NET...
01/24 14:54:36 Information [main] - Starting Monitoring...
01/24 14:54:36 Information [main] - ColdFusion started
So will need some of the log before the start. Not sure what we are looking for yet so for now probably more log the better until the issue gets narrowed down. Then again I might be on the wrong track and the OUT log will not show any salient problem and we need to look elsewhere. Most recent detail is at end of log file. When the log file gets to 200k it will copy and truncate so detail might be in one of the OUTn (n number) files.
What is CF9 version, updater1 applied, CHF1 applied?
