I've enabled logging, the result is on http://www.irk.fm/files/tmp/gpsvc.log - I see the gap in it, but there are no clear error messages or warnings. I mean, error message is here but not really clear - GPSVC(2e8.a24) 19:56:07:309 CGPNotify::UnregisterNotification: Entering with event 0x298 GPSVC(2e8.a24) 19:56:07:309 CGPNotify::AbortAsyncRegistration: No asyn registration is pending GPSVC(2e8.a24) 19:56:07:309 CGPNotify::UnregisterNotification: Exiting with dwStatus = 0x0 GPSVC(3b4.194) 19:56:07:340 CGPNotify::UnregisterNotification: Entering with event 0x204 GPSVC(3b4.194) 19:56:07:340 CGPNotify::AbortAsyncRegistration: No asyn registration is pending GPSVC(3b4.194) 19:56:07:340 CGPNotify::UnregisterNotification: Exiting with dwStatus = 0x0 GPSVC(2e8.2f8) 19:56:40:741 CGPNotify::RegisterForNotification: Entering with target Machine and event 0x29c GPSVC(2e8.2f8) 19:56:40:788 Client_InitialRegisterForNotification: User = machine, changenumber = 0 GPSVC(2e8.2f8) 19:56:40:788 Client_RegisterForNotification: CheckRegisterForNotification returned error 0x6ba GPSVC(2e8.2f8) 19:56:40:788 CGPNotify::RegisterForNotification: Service not RUNNING. waiting GPSVC(2e8.2f8) 19:56:40:788 CGPNotify::RegisterForNotification: Trying to recover from error 1722 - it's 33 seconds delay.
