Hello Bogdan, Upscaling error is didn't show up any more in logs at least I didn't so it. Might need trigger bigger load.
do you do auto-scaling only for TCP ? Our setup in most multi homed, as example public side TCP private side UDP Now, about the TCP downscaling - I guess you see as terminated by OpenSIPS the TCP conns anchored in the process that is terminated ? Yes, that how is look like end result that opensips start blocking TCP connections. If specific process handle sip registration via tcp and opensips trying close to down scale end point need send re register in order do not loose registration. Other wise it cause stale connections. Just close properly connection not enough I think. volga629 ----- Original Message ----- From: "Bogdan-Andrei Iancu" <bog...@opensips.org> To: "OpenSIPS users mailling list" <users@lists.opensips.org>, "Slava Bendersky" <volga...@networklab.ca> Sent: Thursday, March 14, 2019 1:45:20 PM Subject: Re: [OpenSIPS-Users] auto scaling Slava, What about the upscaling error you originally reported ? is there any way to reproduce it ? do you do auto-scaling only for TCP (no UDP,timer) ? Now, about the TCP downscaling - I guess you see as terminated by OpenSIPS the TCP conns anchored in the process that is terminated ? Is is a proper close of the connection ? or ?

More or less, my question is : what was the process creation/termination history before getting that bug log ? Also I just pushed a small commit to improve the date provided by the bug log. In regards to the "not clear how to calculate"...could you be specific ?
