I have one of my PO's that recently stopped running manual GWCHECKs for most users (I had 1 complete out of 10 tests). When I run it, the monitor is showing no activity in the "GWCheck Scheduled Queues". I'm also not seeing an entry in the PO log file showing that it's processing the Admin Task for Mailbox/Library Maintenance (other that the 1 user that did complete). I've stopped/started the PO and looked in /store/postoffice/wpcsout/chk. I only see the overnight maintenance .ckl files as well as the manual test .ckl that ran, nothing of the other GWCHECKS. I haven't seen this issue before. I'm not sure what my next step would be. Rebuild PO (wphost.db)? or something else.
