[asterisk-users] Queue forks asterisk and then leaves the extra processes lying around

[Nigel Roberts]

Hi,

I have a problem with Queue where by a call comes in to the queue and
if all the phones are busy and the queue reaches the timeout, it will
fork a process and leave it sitting there before going off to the next
step in the dial plan and continuing normally. This doesn't cause any
problems except for I assume that it will eventually use up all the
memory on the machine and it messes with my process monitoring.

It doesn't seem to matter what I have as the next step after the Queue
command and it happens only sometimes. It seems like it might even be
a timing issue given that it's less likely to happen if any one of the
phones ring.

The new asterisk processes that get started up look like they think
they're new asterisk instances or though they don't actually do
anything or interfere with the first asterisk instance.

Has anyone had any problems like this? Am I doing something wrong?

The appropriate part of my dial plan looks like this:

exten => 101,1,Answer
exten => 101,n,GotoIf($["${CONTEXT}"="from-internal"]?USERCID:SETCID)
exten => 101,n(USERCID),Macro(user-callerid,)
exten => 101,n(SETCID),Set(CALLERID(name)=${CALLERIDNAME})
exten => 101,n,Set(MONITOR_FILENAME=/var/spool/asterisk/monitor/q${EXTEN}-${TIMESTAMP}-${UNIQUEID})
exten => 101,n,Queue(101|tr|||30)
exten => 101,n,Goto(ext-local,83,1)
exten => 101*,1,Macro(agent-add,101,)
exten => 101**,1,Macro(agent-del,101,101)

and from queues.conf

[101]
wrapuptime=0
timeout=15
strategy=ringall
retry=5
queue-youarenext=
queue-thereare=
queue-thankyou=queue-thankyou
queue-callswaiting=
music=default
monitor-join=yes
monitor-format=
member=Local/88 at from-internal,0
member=Local/83 at from-internal,0
maxlen=2
leavewhenempty=no
joinempty=Yes
context=
announce-holdtime=no
announce-frequency=0

and some logs to show what I mean by the new asterisk process thinking
that it is actually a new asterisk.
