We're upgrading our 7280 running 3.7 to 4.0. We've come across a potential problem that was wondering if people elsewhere have seen.

After the upgrade, users start to see performance degrade and some devices are locking up and rebooting. Not sure why this is, possible JVM / memory issue.

Has anyone else seen this? If so, any ideas on how to "fix" it?

start to see performance degrade

This is inevitable. More features were added and more memory is being used. In my experience, if you don't mention it to people 99.9% of them won't notice.

For lock-ups and reboots, it may be a corrupt database. Execute a wipe-handheld and then resync it without loading the backup and see if it persists.
