We are using ZAM v7 sp1 and for some reason our scheduled alert reports
have stopped running.

I stopped and started our WebConsole/TomCat service and reports run for
a couple of days and stopped again.

The reports that were created and stored under 'Scheduled Reports
output' look like they are there but when you try to access them you
get the following message

'Unable to complete details'

Some questions I would like your help with.

Any reason why they would just stop running?
Have you come across this before?
Were do the reports get stored? Within the filestore or tscdata?
