Error description
Archiving a track or process app with a lot of un-named snapshot can be very slow. This can also lead to resource or memory issues on the messaging server, especially if there are over 15,000 associated snapshots. Un-named snapshots are created each time the process app is saved. This archive process can also block the Process admin console and any queries against the snapshot table for the duration due to the updates being made on that table. Out of memory issues might be seen on the messaging server if the number of snapshots is large enough.
