hi
if is similar to R3 then this imho happens when the server is stopped/restarted and there is many reasons for this - e.g. the reports takes too much resources, or the report is scheduled to the maintenance/restart window or the processing takes too much time at some time (eg during the night where there is some backup activity but usually duringthe day it runs smoothly)…
search in event viewer/logs if the processing server was restarted and it’s reason…
Thanks for the response.
The report is small and the server is restarted on every weekend as part of maintenance activity. Other reports work fine though.
Schedule is done at 5 pm and no busy time there.
Any more inputs?
