Gromit:
We are experiencing the identical problems. Event log no longer works, when trying to configure, the configuration page says "No oid". The M11.cfg keeps getting corrupted when restarting the service. By salvaging that file or making a backup copy while it's working we can get the logging working again. We still have no luck in getting powerchute to stay running. Most of the time when it loses connections it re-establishes, however this can't be counted on. It lost connection about 10 times yesterday alone. We currently have a ticket open with APC (for the last 3 weeks), and I agree, their TS is not very T! Are you using dual or multi processors on your server? They have set up a "test environment" using dual processors, but cannot seem to replicate our situation. All cases I have heard about with this issue so far are with 2 or more processors. APC has suggested that they disable all but one processor. Lame.
