Recurrning instance did not start at specified time

Hi, All,

Version BO XI R2.

We have a daily recurrning schedule that starts at 02:30AM every morning (Deski and Crystal Reports).

For some reason, today they did not start 02:30AM and were still on RECURRNING status in History tab though time has passed on around 03:30AM. But they ran immediately when I restarted the Connection, Deski/CR Job and Deski/CR Page servers.

The schedule ran OK yesterday, but had the same issue day before as well.

I have found no errors in events logs (application and system).

CMS and job and page servers are in different Windows server and clustered environment.

Can anybody got help me on this issue please ?

Many thanks in advacne.
