[Freeswitch-users] recvEvent causes zombies process

[Ejay Greeves]

I have added the second suggestion you made, so far I done it this way because it was easier to get the result. Is it correct how I have done it and if so does it take less resources the other way you suggest because at this stage I don't yet that


loop do	event =
 con.recvEvent       Signal.trap('CHLD', 'IGNORE')	pid = fork do

	end
	Process.detach(pid)	end

you are calling fork every time you receive an event.you need to exit the process from the child and reap or ignore it on the parent.

I am wanting to code an inbound event program.

In order to see why I am getting zombie processes I stripped out all my code and used the minimum skeletcon code to do a test.
con = ESL::ESLconnection.new('127.0.0.1', '8021', 'ClueCon')
con.events("plain", "CHANNEL_HANGUP_COMPLETE")
loop do	event =
 con.recvEvent		pid = fork do		

	end
	Process.detach(pid)	end

This code does nothing but wait for an incoming event, creates an fork then detach however it still produces a defunct process.

I think con.recvEvent is the cause?
