I have problems with my Seaside 2.8 app on a VW7.6 image on Windows XP.  After some number of hours, even if I hardly use the app, the VM will get very slow and then crash with a protection violation.  I'm not doing anything fancy such as calling APIs.  An earlier version of the same app running on VW7.4.1 and Seaside 2.6 will usually run for months without anything bad happening.  I've tried using the VW7.1.1 VM with no improvement.

Anyone else seeing this sort of problem?

Correction.  I meant to say that I tried using the VW7.7.1 VM, not 7.1.1.

That's odd, I'd expect VMs before 7.7.1 to crash more often given the
improvements that have happened over the years.  I am also curious about
what causes the VM to crash.  Could you run your application with the
assert or debug console VMs, and see if there is any interesting output
before the crash?

Gets very slow and then crashes sounds suspiciously like memory
consumption growing indefinitely to me, either Smalltalk memory or a
leak of OS memory of some sort.

Yeah Alan, that does sound like a memory consumption problem but it
doesn't seem to be.  It doesn't give me a low memory warning, I didn't
see any indication of runaway garbage collection and the machine
doesn't slow down, just the VW image.  When I get a chance I'll give
it another try and check memory consumption more carefully.
Perhaps it may benefit me to create a clean image from visual.im.  I
wonder if it's worth mentioning that I was running another Seaside app
on the same box based on VW7.4.1 and Seaside 2.6 at the same time.

I thought to try my application on Linux to see if I would have the
same trouble.  My Seaside app (a version of Run BASIC for mobile
users) has been running 6 days now without a glitch on VW 7.6 and
Ubuntu 8 and only 512MB RAM (the problematic Windows XP box has 2GB).
I wonder if it will run so well on Windows 7.  I will need to go
purchase a license and upgrade one of my machines to give it a go.
