How "pretty" high of a load is that, in terms of "calls-per-second" and 
"max-concurrent-calls"?  Q_MALLOC_DBG will typically add +30-50% to 
shared/private memory usage, as well as maybe a 10% increase in CPU 
usage.  But OpenSIPS uses very few CPU and memory to begin with, so it 
will be quite safe to do.

My advice: unless you're running more than 50 calls-per-second through 
it, there is no need to even start worrying about Q_MALLOC_DBG altering 
the system's behavior.  Below the 50 CPS level, the difference is 
unnoticeable.

Yes, it's a "opensips" binary command-line option.  The man page needs 
updating, indeed, however you could try "opensips -h" and you'll see 
that option.
