We are having a recurring problem where the maintenance_mode probe stops working. Although the probe status shows as green, schedules which should be active appear as inactive in UMP and alerts are not suppressed. We fix it by restarting the maintenance_mode probe. We have scripted a daily restart of the probe but lately (over the last few weeks) it seems a daily restart is often not frequent enough. I have submitted log files to CA support who can't find any obvious errors. Unfortunately we are running an EOL version of Nimsoft (v7.5; maintenance_mode v1.00) so CA is unable to escalate to higher level support. We are in the process of planning an upgrade but due to internal delays this will likely take a few months. I was wondering if anyone might have experienced this problem and found a solution?

Hi,
The maintenance_mode probe in 7.x has a "clock drift" problem where maintenance schedules will fire at the wrong times (or appear not to at all). Additionally there are some issues caused by overlapping maintenance schedules (e.g. a machine may be in two schedules and only one will work.)
The maintenance_mode probe version 8.20 corrects these issues and it's actually safe to run that probe in a NMS 7.x environment, so if you're not able to upgrade the full installation to UIM 8.x you can still take advantage of this fix.
You can find a copy of the new probe version on the UIM Hotfix Index Page.
Note: the hotfix page lists NMS 7.6 but it will also work with 7.5.
