Re: [sr-dev] [kamailio] debugger: kamailio freezes when dynamically setting module level(using fifo/rpc), if the module level is not previously set in config file: ```modparam("debugger", "mod_level", "core=2")``` (#463)

This is a recursive access to the same slot in debugger hash table:

* lock the slot to update its list of items * do shm malloc which does internally a log message which needs to get the value of the log level of an item on that slot

Solutions:

* make the locks reentrant (perhaps the safest in long term) * reorder the sequence of code so the shm malloc is not done under the lock (under lock do only insert/remove of the item, but allocation/free of item must be done outside of lock region)
