 Have you checked if there is traffic on looping on your OpenSIPS ? maybe 
 due bad routing, OpenSIPS is keep sending to itself some traffic,

Hi Pasan,

I doubt that fix_route_dialog() is doing something wrong :D. Maybe there 
is something wrong with the signaling / cfg. After the call is 
established, do a "opensipsctl fifo dlg_list " to see the dialog 
details as learned by OpenSIPS.

"Using t_on_reply() is harmless as it simply set a holder in the msg/transaction,

My problem was that server received 407 replies from its own source ip :/. I 
couldn't figure out what triggered it. Anyhow issue resolved after I removed 
fix_dialog_route() function which causes  BYE to send to a private ip of a 
NATed device. I have fix_nated_contact() before create_dialog() function but 
dialog data seems to have unmodified contact data which I believe is fixed in 
2.4 as you mentioned.

  "So the bottom problem for you is why the processes stuck ? do they stuck like

All traffic processing workers were stuck in a loop and consume 100% CPU. I 
couldn't get much debug info like running opensipsctl trap when issue occured :/

Anyhow now I'm planning to upgrade thee system to 2.4 this year which has 
support till 2021.
my sip cluster is now  stable without fix_dialog_route() function.

Hi Bogdan,

Thanks for the reply. writing inline replies


"Using t_on_reply() is harmless as it simply set a holder in the 
msg/transaction, nothing more. And a locally generated reply does NOT trigger 
on_reply_route - this route is triggered only by *RECEIVED* replies."

My problem was that server received 407 replies from its own source ip :/. I 
couldn't figure out what triggered it. Anyhow issue resolved after I removed 
fix_dialog_route() function which causes  BYE to send to a private ip of a 
NATed device. I have fix_nated_contact() before create_dialog() function but 
dialog data seems to have unmodified contact data which I believe is fixed in 
2.4 as you mentioned.

 "So the bottom problem for you is why the processes stuck ? do they stuck like 
consuming cpu (doing some crazy looping) or blocking in some I/O (no CPU usage) 
?"

All traffic processing workers were stuck in a loop and consume 100% CPU. I 
couldn't get much debug info like running opensipsctl trap when issue occured :/

Anyhow now I'm planning to upgrade thee system to 2.4 this year which has 
support till 2021.
my sip cluster is now  stable without fix_dialog_route() function.

Re: [OpenSIPS-Users] locally generated replies

[Bogdan-Andrei Iancu]

Hi Pasan,

Using t_on_reply() is harmless as it simply set a holder in the 
msg/transaction, nothing more. And a locally generated reply does NOT 
trigger on_reply_route - this route is triggered only by *RECEIVED* replies.


So the bottom problem for you is why the processes stuck ? do they stuck 
like consuming cpu (doing some crazy looping) or blocking in some I/O 
(no CPU usage) ?
