Hi,

Given several EVAPI worker processes:

   modparam("evapi", "workers", 4)

   # kamcmd -s /run/kamailio/kamailio_ctl ps | fgrep -i evapi
   539257       EvAPI Dispatcher
   539258       EvAPI Worker
   539259       EvAPI Worker
   539260       EvAPI Worker
   539261       EvAPI Worker

How should one understand the way that the EVAPI workload is allocated among 
them?

My best guess is that the EvAPI dispatcher process is the sole accept()or of 
client connections and the place where all relaying to client connections is 
done, regardless of their number, and that the ‘workers’ represent an async 
pool of processes in which TM transactions can be resumed or other work can be 
done when an outside caller sends a message to the dispatcher.

However, the documentation[1] is a little vague on the meaning of the ‘workers’ 
modparam:

   "Number of worker processes to be started to handle incoming messages from 
remote applications.”

Or maybe it’s not. Just wanted to confirm that my understanding is correct.

Thanks!

— Alex
