I am running V9.1 rev 4691 on Windows 2000 SP4 using SQL 2000 SP3, all on the same machine. This config has been running fine for at least a year. About 2 weeks ago the scheduled nightly backup job quit running. If I reboot the server it will run OK for 2 or 3 days and then quit. There is no apparent pattern. It just hangs in the scheduled state. Ther are no alerts pending. The tape is inserted as usual. It never goes into the out-of-time-window state. It just stays in the scheduled state. If I stop & restart the BUExec services, it will then switch to the out-of-time-window state. I notice in looking at the alert history, that there may be a problem with BEDB maintenance. Maintenance is scheduled every day at 4AM. On the days when the job fails to run, there is no alert message showing the results of maintenance. The alert message showing that maintenance has started is there, but the corresponding status message is not. In my case, maintenance normally takes about 45 seconds. I can look in the data directory and see that the backup of bedb is being made. I can also look in the SQL log files and see the same thing. But the alert message showing the results of maintenance is missing. Maintenance may not have anything to do with this issue, but I thought it was odd that the alert message was missing. Any ideas on what to do?
