Description
After the latest changes to the handling of the implicit sets in the S-CSCF, deadlocks might happen but only on use of implicit sets. For example, if there are 2 de-registrations for 2 identities coming in parallel, it is possible that they will lock each-other out! The problem lies in the need to lock 2 public identities at the same time, from calls in registrar_timer and update_contacts.
