Schedule jobs start twice

[dafna]

Hello,
Lately we are having problems with schedule jobs – some of them starts twice on the scheduled time.
Recreating the jobs did not help.
I think that the problem may have started after the end of the Daylight saving time period.
We are using cognos 8.1 with 5 different dispatchers.

Can someone help on this subject?

Thanks,
Dafna.
