asterisk users - May 2016 - Taskprocessors

Hi,
Trying to move traffic from one of our asterisk gateways using 11.21 to 
a newly installed using 13.8.0/13.9.0-rc1.

After half an hour with peers just registering and no calls the 'core 
show taskprocessors' shows between 4500 and 5000 processors.

the ones that there are a lot of is

subp:SIP/<peername>   2  0   2

Doesn't look right to me that there should be so many
'hanging/waiting'

using Centos 7 / and sippers are via odbc.

Initialy I had a lot of subm:...  hanging and these processors would 
take 5 seconds to repond to a ping and jobs in their input queue would 
newer be finished.
That problem did disappear when sippeers was updated with 
subscribemwi='yes'.

Can someone give me a hint, I have installed a lot of asterisk systems 
but never stumpled upon this before.

b.r.

How many SIP peers do you have? Taskprocessors can be ephemeral or can 
be created to stick around for quite awhile.

This would definitely be concerning. Can you provide full details on an 
issue[1] including attempting to reproduce the above and get a backtrace[2]?
