We're having a strange problem with one of our ColdFusion servers. We're
running on Win 2K3, IIS 6, CF 7.01 and Java 1.4.2_05.
The web server will stop responding altogether. It will not serve up HTML
or CFM pages. Now, we've seen this before in the past, when the hook
between IIS and CF has been hosed up, but usually when used to see this,
JRun would go to 100% CPU and hang up. But with this problem, we're seeing
the opposite. JRun is running at almost 0% CPU when the web server stops
responding. There is no load on the box at all, during this time, and we're
getting a boat load of the following error:
java.net.SocketException: Connection reset by peer: socket write error
I know this can be cause by at least the following three reasons:
client's browser has been closed.
client's connection has been disconnected.
client presses the stop button.
Now, short of rebooting the box, the system admins have tried disconnecting
and then reconnecting (via the Windows interface) the NIC. It seems to help
for a short time. During this time, you can still Remote Desktop in, so I
don't think it's a true NIC problem. It "feels" like a Windows/IIS issue
but we can't find anything in the logs to help us troubleshoot. I don't
think it's an actual NIC or NIC driver problem, because during this time,
you can still Remote Desktop in. If the box is completely re-booted, the
problem seems to go away for a couple of days, then it happens again.
Has anyone seen anything like this before. Up to this point, this server
has been running quite well. Now this out of the blue. One thing I can
point to is that this problem "seemed" to start immediately after the latest
rounds of Windows updates - however the System Admins have rolled them back,
and it still persists - so I'm not sure if that was merely co-incidence or
not.
Any input is appreciated.
Kind Regards,
Dave Hannum
