A similar thing happened to me and the cause of the memory saturation was a
security site I had used RDS security or advanced security. If you are using
the native cfauthenticate cfauthorize tags in a security setting, go look at
siteminder in perfMon and see how much memory it has tied up. It seemed
unrelated at the time I had problems, but replacing it with another solution
for security remedied the problem.

Subject: OT BUT URGENT: IIS stability
| Hi guys (& gals)
|
| Sorry for the OT post, but I REALLY need help on this one, people's jobs
| are on the line.....
|
| We have a serious problem with stability on IIS 5, Win 2K, CF 4.5.2. IIS
| has suddenly started to die. Symptoms include -
|
| - Existing virtual directories get "lost". VDir's that have been working
| fine for 6 months suddenly return "This page cannot be displayed" IIS
| errors. If you delete the VDir and recreate it, it works again.
|
| - CF pages take forever to return. Flat HTML pages are responding
| reasonably well, but all the images now take forever to download.
| Restarting the CF service seems to help, but only for about half an
| hour, then it returns.
|
| - FTP transfer rates have gone down from over 200K / second to about 5
| BYTES / second.
|
| My first thought was a runaway CF process somewhere, but when we look at
| performance monitor on the CF/IIS server, CPU usage is only at 5% and
| memory usage is minimal. Then we thought it might be persistent database
| locks, but we've eliminated that. Performance monitor on the DB server
| shows only minimal CPU / memory usage too.
|
| We have CF and IIS on one server (Dual PIII 800, 1.3GB RAM) and SQL
| running on another. The SQL server is set up as the domain controller.
| CFSTAT shows that the database response time is fine, it's just taking
| ages for requests to get to & from the server.
|
| I know that at my last job, IIS was rebuilt as a regular maintenance
| task every two or three months. This installation of IIS has been for
| the last five or six months until this last week. And no code has
| changed in the last three weeks.
|
| Has anyone else had similar problems? How often do you all have to
| rebuild / re-install IIS ? I need some figures to give to the management
| ASAP, as they're starting to growl for blood.
|
| Mail me directly if you like
|
| Cheers,
