I am also having the issue where CatDumb is cutting off the text file it outputs to. It stops as soon as it reaches a size of 14,333KB. I installed hotfix 19 per the instructions above but still have the same result.
When CatDump is run the following is in the Event Viewer:
Faulting application CatDump.exe, version 0.0.0.0, faulting module msvcr71.dll, version 7.10.3052.4, fault address 0x0002cf20.
I am running:
BackupExec 10.1 Rev 5629
Windows 2003 Server SP1
