What about sql_query_async()? I assume that uses core async_workers too.

What kind of traps? :-) I don't really see anything in the docs for 
async_asleep() that sets off alarm bells in my mind.

At the moment I'm only using async_route(), yet this is the process 
situation:

[root at allegro-4 routes]# kamcmd -s /tmp/kamailio_ctl ps
27621	main process - attendant
27623	udp receiver child=0 sock=10.150.20.6:5060
27624	udp receiver child=1 sock=10.150.20.6:5060
27625	udp receiver child=2 sock=10.150.20.6:5060
27626	udp receiver child=3 sock=10.150.20.6:5060
27627	udp receiver child=4 sock=10.150.20.6:5060
27629	udp receiver child=5 sock=10.150.20.6:5060
27630	udp receiver child=6 sock=10.150.20.6:5060
27632	udp receiver child=7 sock=10.150.20.6:5060
27635	slow timer
27638	timer
27639	secondary timer
27641	Async Task Worker
27642	Async Task Worker
27644	Async Task Worker
27647	Async Task Worker
27650	Async Task Worker
27652	Async Task Worker
27654	Async Task Worker
27656	Async Task Worker
27658	MI FIFO
27661	ctl handler
27663	RTIMER USEC EXEC
27664	RTIMER USEC EXEC
27666	RTIMER USEC EXEC
27669	RTIMER USEC EXEC
27672	RTIMER USEC EXEC
27674	RTIMER USEC EXEC
27676	RTIMER USEC EXEC
27678	ASYNC MOD TIMER
27680	ASYNC MOD TIMER
27682	ASYNC MOD TIMER
27684	ASYNC MOD TIMER
27686	ASYNC MOD TIMER
27688	ASYNC MOD TIMER
27690	ASYNC MOD TIMER
27692	ASYNC MOD TIMER
27694	Dialog KA Timer
27696	Dialog Clean Timer
27700	tcp main process

So it is safe to remove the async_workers declaration entirely or set it 
to 0, and I can still benefit from 8 async processes for async_route()?
