[asterisk-dev] Failure to write to tcp/tls socket

[Chandrakant Solanki]

Hi All,

Asterisk ( Server) Details ...
Asterisk Version*: 1.8.13.0*
OS: *CentOS 6*
CPU: *Intel(R) Core(TM) i3-2100 CPU @ 3.10GHz*
RAM: *4 GB**
*
Started listening asterisk on UDP (5060) 'n TLS (5061) ports. I would like
to reach maximum running call capacity on Asterisk machine, but after so
many testing, just reach on 1200 calls at a time.

Set *maxfiles=65536* in asterisk.conf, and *rtp 10000:50000.*

I am using *SIPP* tools from another machine, which is Ubuntu system,
configuration
OS: *Ubuntu*

While performing call test, after reach around 1000+ calls i received below
warnings on asterisk cli.
