The issue is described in #3350 and the crash is caused when trying to search in `dns_cache.c` [LOCK_DNS_HASH();](https://github.com/kamailio/kamailio/blob/d4629be286fc6d3…. When `dns_cache_init=off`, the lock is never initialized and when trying to lock it crashes. Per my understanding, when `dns_cache_init=off`, no calls to `dns_cache.c` should be made and instead call the alternative ones from `resolve.c`, since the whole functions are compiled only when USE_DNS_CACHE definition is present. Just a question to clarify, what is the reasoning behind USE_DNS_CACHE definition and a separate `dns_cache_init` parameter?
