Hello Daniel, It works fine with “db_op_rui”. Thank you.

I will try to use “db_op_ruid” during the next scheduled restart as it looks to be more efficient for the DB usage. If doesn’t help, “db_check_update” will certainly do the job. Many thanks for your suggestions.

Using ruid avoids this. Another option is to use: http://kamailio.org/docs/modules/stable/modules/usrloc.html#usrloc.p.db_che… But I would go for ruid option, because it is also faster due to single value key.

Do you think that setting “db_ops_ruid” to 1 will solve the issue? I took a wireshark capture while the problem occured and saw that Kamailio make an UPDATE request whereas the location database had no more entry for the username. Also, I look to the MySQL logs and see nothing in particular.

Can you try with db_ops_ruid set to 1: http://kamailio.org/docs/modules/stable/modules/usrloc.html#usrloc.p.db_ops… Also, does database server logs point any error?

After a restart of Kamailio, some username are still in memory and updated accordingly with usual re-REGISTER flow. But the entries in location db is deleted. Kamailio tries to do a SQL UPDATE which fails because of that. So, for each username which are not in location DB, I must do a “kamctl ul rm” and wait for the next REGISTER. The new REGISTER will challenge the UAC for a new Authorization which should result in an INSERT INTO instead of an UPDATE. Can someone help me to solve this?
