This happens fairly quickly though and I would suspect that that you've got something else going on...because that kind of traffic with the issue we've seen would toast your servers much faster than they seem to be dying.

Subject: Maxing out running requests then server hanging -- Help
Everyone,
We put out a new release of our web-application and have been having
server problems problems ever since. All will run fine and then all of
a sudden running requests will start creeping up and then CFMX hangs --
about every 4/6ish hours. Before the new release the most problems we
would ever have was database locks and we could either wait for the
database lock to finish or kill it -- none of this has been database
locks. Majority of the time both boxes (2 web servers hardware
loadbalanced) will be using up about 700ish meg of ram (both have 1 gig
of ram) when they are hung. We tried even running CFMX from a command
line to get a java stack trace when it hangs, but it never would create
a dump of the stack trace for us even -- toooo hung I am assuming.
Then this past week for a solid hour the running requests would keep
running up to the max (25/box) and then would hang -- all we could do
was continually restart the service which we did about 20 times on both
boxes -- we tried rebooting in the middle of all this as well which
didn't help either. The weird thing was after about an hour it all went
back to the 4/6ish hour hand routine.
Any ideas on what could be causing the hangs? Since the new release
used CFC's heavily could this be causing any of the issues? Any ideas
on better ways to trace/debug it?
Here are the details on our setup (all software is fully patched):
2 hardware loadbalanced webservers running Win2K with CFMX 6.1 with
an Apache webserver (2.046)
Seperate box running MS SQL Server
Approximate traffic is 12K to 15K unique visitors/day
Thanks,
Jeremy
