Hi,
Your patch didn't work for me. The kamailio didn't start if i use "if (
_rank != PROC_MAIN)"
So i commented out, both if statement, and now "out of sync problem
disappeared"

BUT
I am experiencing that in usrloc module, still more then one worker
process share the same sql connection:

If you need detailed log/higher log level, then please let me know.
usrloc seems to be using the same connection from multiple processes:

It probably needs a fix like below because mod_init has also created a db
connection which is inherited by at least one child and ul_dbh is not 0 anymore.
That process needs to be excluded from opening a database connection, all
other childs need to open their own DB connection. I just don't know what
rank mod_init is run as and thus don't know which process to exclude. Maybe
some other dev can jump in.
