This problem cannot be related to the time MapScript takes to create the
image, since it is $image->saveWebImage() that returns you the image
URL, and it doesn't return until the image is finished generating.  So
this possibility is completely out of the question.

However I've seen odd disk caching issues with Windoze servers in the
past, sometimes with local disks, but very often with network drives...
I hope this is not running off a network drive?

Also, did you check your server's error_log to look for error messages
that could help figure the source of the problem?

I hear ya!  It's a strange one, but most of the time once we figure the
source of the problem we start wondering why it ever worked.  ;)

Good luck!
