OES2 SP2

Apple MAC OSX 10.6.4

We have huge problems saving files from Adope Photoshop to AFP mount points.
When doing so Photoshop says it cannot save the file due to an unexpected end-of-file (eof)

When connecting via CIFS to the same location, then the file can be save without any Problems.

Al log file while trying to save a file (simpletest.eps) is attached
