Hi Folks,
We faced a deadlock caused by acquiring the same lock twice in
src/modules/dmq_usrloc/usrloc_sync.c
dmq_ul.lock_udomain(_d, &aor);
> lock_get(_d->table[sl].lock);
get_urecord_by_ruid
> lock_ulslot(_d, sl);
>>> lock_get(_d->table[i].lock);
The attached fix will not lock until get_urecord_by_ruid as returned.
Regards
Julien
