Did the crash happen immediately after the upgrade? Or has it been working for a bit? Also do you have a backup made before the upgrade? If the system was stable prior to the upgrade and the crashing started happening immediately after I would restore your backup and regroup. If you don't have a backup I would engage Atlassian support.

I didn't happen right after the upgrade. Once it has lot of people using it we are seeing this behavior.
