[Mapserver-users] Mapserver doesn't create image, no crash

[Möri Cédric]

Hi Berend

sadly engouh I've got no hint for you. We are suffering of exactly the same
problem:

We are running about 15 projects/mapfiles on the same cgi, but the problem
occurs only in one project which worked fine in 3.6.

I reduced the number of layers in the project from about 25 to 10, but still
the same. We tried all your ideas also with no success. We also tried to
eliminate all LABELCACHE and POSTLABELCACHE in the mapfile.

We are running MapServer 4.0.1 on RedHat 7.2. 

If anyone has an idea or the solution of the problem please let me/us know!

Best regards
Cédric
