I haven't checked the details, but let me note the 'tell'ing to the
parent process is not possible.
The reference of 'tell' says
Send .. to .. all children of the current process, and all other
children of the parent process
The parent process is the one thay relays all messages between the
processes. It cannot be the addressee of a messages.
Therefore, as a general rule, the parent should never be assigned any
application tasks (especially not database manipulations, as these are
also synchronized via the 'tell' mechanisms). It should be as
lightweight as possible, just waiting for events and delegating work to
For messages to the parent, you might consider the "@lib/boss.l"
mechanism (I know you have used that in the past), calling 'boss' in the
children and 'hear' in the parent.
So this is to be expected:
