The other day we had a constituent record cause errors (we think) in some queries that were running while a gift linked to a membership was being committed in a batch.  Have any of you had this experience? 

Any thing else I may want to know about Membership module before adding new Categories and possibly 15 more users with access to Memberships?  (We have 500+ authorized users--100 concurrent max--only 5 or so using Membership now.)

 Thanks for any advice!
