Users are sometimes seeing this error when in their mailbox:
GroupWise Error C071 Cannot sync dictionary because read transaction is going or DB is open

Clear the error, sometimes it comes back, sometimes it doesn't. We are not using native archiving. Never had this issue using GW 8 - we upgraded to GroupWise 2014r2 mid May and the clients are being rolled out progressively. Some users who are running GW8 see this error as well.
Not much can be found on it - anything I've seen is archive related but that doesn't apply to us. Any ideas?
