I use GW 8.0 HP1 in caching mode, every 2 or 3 weeks my caching mailbox is
damaged and GW needs to rebuild the mailbox. A standalone gwcheck -
structure rebuild did not fix the issue.

I got the same problem without HP1, but never with GW 7.0.3.

Windows XP SP3 German with all patches. Mailbox size: 4,6 GB.

Any ideas how to resolve this issue?
