Hi!
We have set up a test ATS installation, and after running for some
time it gives us this warning:
[Sep 28 14:39:54.917] Server {0x2adc690b0700} WARNING: too many
connections, throttling

At this time this proxy has around 54.5k connections:
sudo traffic_line -r proxy.process.net.connections_currently_open
54543
This number, multiplied by 1.1, gives 60000. This limit comes from
fds_throttle or fds_limit, as far as I can tell from grepping/ reading
the source (I am no C/C++ programmer, though), but where they obtain
their values I don't know. I have
proxy.config.net.connections_throttle set to 120000. System limit of
open files has been raised to 100000 before starting Traffic Server:
$ sudo grep open /proc/$(pidof traffic_server)/limits
Max open files 100000 100000 files
What should I do? How to raise a limit of total connections? Thanks in advance!
