[SR-Users] kamailio does not responde if an rtpengine is unreachable

Yes, UDP register is sent, but kamailio does not respond to it.

Then I did this.

1) Started K where rtpengine udp:192.26.134.10:6050 is enabled but is
not running.

2) Gave kamcmd command.  It two about two minutes before I got the
prompt.

3) Gave 'rtpengine.show all' command. It took perhaps 30 seconds to
produce:

{
	url: udp:127.0.0.1:6050
	set: 0
	index: 0
	weight: 10
	disabled: 0
	recheck_ticks: 0
}
{
	url: udp:192.26.134.10:6050
	set: 0
	index: 2
	weight: 1
	disabled: 1
	recheck_ticks: 60
}
{
	url: udp:192.26.134.10:6050
	set: 1
	index: 1
	weight: 1
	disabled: 1(permanent)
	recheck_ticks: N/A
}

Now udp:192.26.134.10:6050 shows as disabled and kamailio started to
accept sip requests.

How is it possible that one non-responding rtpengine can paralyze the
whole sip proxy?
