That's what I thought initially. There are around 1000 registrations (mostly TCP) (LUA + Mysql) with timeout of 15 minutes. There are lots of BLFs, subscribes and shared lines, and multiple registrations (average of 3.5, so total of 3500 registrations points). We do ping for keepalive every 3 minutes. I guess increasing ping time and registration timeout to 30 minutes will help. Thoughts? -Jai On Mon, Nov 25, 2019 at 4:33 PM Mike Jerris <mike@freeswitch.org> wrote:
Our code to handle options couldn’t be much simpler. If you are seeing massive delays the only thing I would guess would be that there is some sort of massive ddos type attack causing significant queuing of inbound requests or a register storm and your registrations handlers are getting behind. Take a look at logging and sip traffic around the same time for clues on what else might be happening on this sip profile at the same time.

Hello,
Every now and then we see long delay in response for options. Example in the trace below free-switch took 44 seconds before it send 200 OK.
What will be best way to troubleshoot this?
