We are seeing problems where our regularly scheduled jobs are not running at the expected times. There is nothing in the eventlogs that suggest a cause for this we just end up seeing entries in the log like this:

8/7/2012 1:09:05 AM Debug Next execution (2) for job 'DWAYProd_FENOC_Hourly_YWAYRunBatchRules' is: 8/7/2012 2:05:16 AM
8/7/2012 1:09:05 AM Info Job completed: DWAYProd_FENOC_Hourly_YWAYRunBatchRules
.

8/7/2012 3:32:26 AM Info Job started: DWAYProd_FENOC_Hourly_YWAYRunBatchRules
8/7/2012 3:32:26 AM Debug Job (2945999) was added to processlist: DWAYProd_FENOC_Hourly_YWAYRunBatchRules

Where the job just doesn't run when scheduled. We are not sure what is causing this but sometimes we also see jobs that missed runs such as the above one did (at hours 2 AM 4 AM and 5 AM) then run many times in one hour later one as if the backed up runs are trying to process:

when obviously since this is an hourly job that is only supposed to run 5 minutes and 16 seconds after every hour that should not be running at any of those times. I will attach a log and a screenshot but this problem seems to have popped up overnight.

I had to break the log into 2 files because the attachment was too large as one file and the upload timed out, but when concatenated they are all of the logging from today so far.
