I see several errors in the server logs that say:

SQLSTATE[42000] [1226] User 'scholarships_app' has exceeded the 'max_user_connections' resource (current value: 10)

A couple of these occurred near the timestamp show for this bug report being filed.

@Praveenp Thanks for pointing this problem out. We had configured the backing database server to throttle concurrent connections but apparently set the limit too low. We have raised the limit from 10 to 50 and I'll keep an eye on things to see if that is enough.

Sean raised the limit for the app and I removed the use of persistent connections. Seems to have fixed things.
