Attached to Project - sip-router Summary - modules/usrloc deadlock on load/restart Task Type - Bug Report Category - Modules kamailio Status - Unconfirmed Assigned To - Operating System - Linux Severity - Critical Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - Hi,
kamailio stops responding when location and location_attr table contains non expired contacts and attributes.
I have these settings for usrloc module:
modparam("usrloc", "nat_bflag", FLB_NATB) modparam("usrloc", "xavp_contact", "ulattrs") modparam("usrloc", "db_mode", 2)
output of 'bt full' is attached.
function uldb_preload_attrs locks table by lock_udomain function and then calls get_urecord_by_ruid which again try to locks table.
Workaround by removing lock/unloc domain helps, but then operation is not atomic.
Regards, Seudin
