A customer had the error that scheduled reports where not sent out from the SCOM 2007 R2.
In that case, the status of these schedules where: Error: Thread was being aborted.
There was no more error in the eventlog or any other location that pointed out to an error.
Also if the reports where opened from the opsmgr console, they where shown fine.
So one thing we figured out was, that the time slot for the reports was really big.
For example: Get CPU-Usage Performance for 5 Servers for the last year.
So we had a look at the server usage at the time when the scheduled report should have run and found that the server was under big pressure at that moment.
We recommended to move the reportingservices to an other machine for running the reporting services only and to spread the reports all over the days.
Now also big reports are generated as requested.
