[OpenSIPS-Users] uac_registrant preferences

[Ovidiu Sas]

Do you have any server that is timing out?
The registrations are handled sequentialy and if a server is timing
out, then it will take a long time for opensips to handle all the
records in a slot and it may overide with the next scheduled timer
task for the next slot.
Try to increase the number of slots (hash_slot) and the timer interval
parameter.
