First request to application throws 500 error

[David Aden]

We're on an Windows 2003 box with IIS. After the app is inactive for awhile
users will get a 500 error but if they request the same page again, it displays
fine.

We've done a variety of things including setting an IIS keep alive type of
parameter way up, but the error continues to show up. The problem exists across
applications which have worked fine in other environments so it doesn't appear
to be application-specific.

Has any one run into a problem with CF 7 not working when you first hit an
application, then starting to work after that?

Any suggestions for solutions?

I've been trying to resolve the problem looking exactly like this for a while
now. Unfortunately I don't have a solution so far.

In our case I noticed that IIS returns HTTP 500 after some inactivity not only
for ColdFusion pages, but for other files as well (.js file for instance). This
got me thinking if it's ColdFusion-related at all.

There is still a chance it's somehow related to ColdFusion, since by default
it seems to install a wildcard application mapping for its connector.

Anyway, this might give you a couple of ideas on where to start.
BTW, try checking IIS logs for win32 error code - might be it'll shed some
light on the problem.

Please let me know if you happen to manage to resolve the issue.

Thanks in advance

David,

sometimes Microsoft Internet Explorer report 500 error, and does not show
debugging nformations about error.

Use firefox to request your page, and you will have the full error report, and
not just a 500 error return.

The solution to our problem appears to have been found.

The box administrator noticed that IIS was installed after SP1 (this is on
Windows 2003). Apparently, this leads to IIS throwing some 500 errors. He
re-applied SP1 to the box and the problem seems to have gone away.

I'll post something else if this doesn't answer it, but he found this late in
the week and it seemed to handle the problem.
