I encountered this problem last week. I ran GTP then from the job management in Contributor I could see the status of
Validity Users: Cancelled
Reconciled: Cancelled
Cut Down Tidy: Cancelled..
these are automatically cancelled in like 10 secods after I click GTP..
then Cognos support told me to reset the server, and I did. It was working for 2 days and now I just had the same problem again..reset the server but still not working... our server has 4 GB of Ram..is this the issue?
Let me know...
Which version are you running? Older versions often hade problems with the com+ component so it could be a good idea to automatically restart it before every job that should run.
How many cpu:s does your server have?
What is written in the planningerrorlog when the reconcile is canceled?
