RE: Bug In Miva Engine or just Scripting Error

I've only run the VM on Windows. What version of IIS is the server =
running?
Does the application handle a lot of requests?

Now that I think of it, I developed an application for a company that =
had
the same problem. Intermittent crashes. We had to restart IIS every =
couple
days (Win2k AS). I never did figure out trace it down to exactly why.

I've since moved to Windows 2003 for all my Miva development, and I've =
not
had any trouble since last year (except self-inflicted problems =3D). =
BTW, IIS
6 ISAPI handling is much more stable that its predecessor (probably not =
what
you wanted to hear though).

Ben

P.S. If you want, you can run the application on my Win2k3 server and =
see if
the same problem happens. Contact me off-list.

No, it's not consistent, and only occurs "sometimes". It also only =
occurs
on windows-based servers...seems to be tied to system load.

And while I agree that the VM appears pretty stable under Linux, have =
you
tried any under Windows?
