we have had CF problems on our win2000 server, which appear to be related
to CFHTTP. ColdFusion service has hung on numerous occasions (i.e. service
not actually stopped, just failing to reply to requests - though sometimes
continuing to log).
There seems to be two possibilities, which I will be looking into...
CFHTTP is memory hungry and CF4.5 does not release memory once acquired, so
it's possible that CF is simply running out of memory. I doubt very much
that this is the case as the server has 1GB or RAM and the CF app server is
not heavily used (the site is primarily developed in ASP), so peak memory
requirements should not be too high (and therefore the max memory reserved
by CF for it's own use should not be too high either). I've added
performance counter logging anyway to see if this is causing the problems.
The other possibility is that CF has some problem using the wininet.dll
provided with 2000. I've never had these problems on NT4, on which CF
copied a version of the wininet.dll into the coldfusion\bin directory, and
the problems only started on the win2000 machine when a new application
which heavily uses CFHTTP was installed.
Since adding timeouts to all CFHTTP calls and tweaking some settings in the
CF administrator (request timeouts, restart after blah failed requests
etc.) and the services control panel it does seem to be pretty stable. I've
also started logging every processed .cfm request (simple cffile operation
in the sites application.cfm) and have adding monitoring from another
server with notification via email and SMS, so I'm relatively happy to
leave it alone until I have time to look into it in detail again. At least
next time it falls over I'll know about it and I'll have some more logs to
check to see if I can find out what the problem is.
BTW, it is CF Pro that we are running.
