Comment 8 for bug 815928

FWIW, I still get HTTP 500 sometimes when attempting to access or search in the email/account views, and sometimes when attempting to delete users. The frequency seems to depend on timing; during the busiest hours this can happen as much as 2/3rds of the time, and during light traffic hours it's more like 1 in 10.

The Nexus admin UI helped quite a bit, but the root cause is still there.

I suspect the proxy may be timing out when SSO tries a database operation that takes too long.
