I have many files (503 files, 600MB) in the ZENworkszpmdist folder there
for several days now but no vulerabilities and no bundles created. CPU is
not busy.

Version 10.0.1 on Windows 2003 SP2.
The server and two XP workstations as registered devices.

This sounds like the same problem that Alicia has been asking about. What
am I missing?
