---------------------------------------------------

Hello Joshua,

after analaysis, we check that there is an action that takes long duration and keeps the channel of each call open for a long time. This action is the following:

Line 59743: [Feb  2 10:21:12] VERBOSE[4189812][C-000000b3] pbx.c: Executing [h at guest-access-whc:4] Set("PJSIP/opensips-vmss-000000b2", "DESTINATION=xxxxxxxx74") in new stack
Line 96218: [Feb  2 10:21:57] VERBOSE[4189812][C-000000b3] pbx.c: Executing [h at guest-access-whc:5] Set("PJSIP/opensips-vmss-000000b2", "PENDING_SMS_ID=") in new stack

We also took the logs that you mentioned and a core dump for this action. This is a query in the DB as you can see from the core file.

Could you please check them?

> Hello,
> we have built a Voicemail platform for Telecom services in a Telecom Client based on Asterisk (18.6) and Opensips (3.1.0). Below you can find some details for architecture:
> •	SIP signaling from Core Network
> •	2 proxy opensips VMs for the incoming calls (load balancer to asterisk VMs) and outgoing calls 
> •	3 asterisk VMs for handling the calls with built dialplans based on phpagi (asterisk conf files and PHP-AGI files) – We call phpagi scripts to call procedures from the DB or for some other processes.
> •	The Data for user settings are stored in external DB (ORACLE in different VM)
> •	The data for file storage (voicemails etc.) are stored in NFS
> We have (and still are) faced serious problems in the service (in queues of PJSIP processor) , when we transfer more traffic from the core system (increase of active calls/Asterisk), without this traffic being so huge in order to justify the problems in the voicemail service. The resources of Asterisk have 12 CPU cores, 32GB RAM without reaching above the 50% when the problem occurs.
> This causes delays in call processing and the problem is increasing until the service cannot support any call. During this problem, the active calls in Asterisk are increasing when the queues are reaching the limit. (we have not any issue until ~100 active calls/Asterisk).
> Have you ever faced the same problems?
> We need your support since it is a production issue and affects the service.
> Br,
> Spilios G.
