[asterisk-app-dev] Error TCP_NODELAY on HTTP connection.

[Sadeesh Radhakrishnan]

Hi,
we are using certified asterisk version 13.8-cert4
the calls land through ARI Stasis application,
it was working fine for some time and all of sudden, we got the following
error,

[Jan 18 05:53:56] WARNING[13686]: http.c:1946 httpd_helper_thread: Failed
to set TCP_NODELAY on HTTP connection, getprotobyname("tcp") failed

[Jan 18 05:53:56] WARNING[13687]: http.c:1946 httpd_helper_thread: Failed

[Jan 18 05:53:56] WARNING[13687]: http.c:1947 httpd_helper_thread: Some

Can somebody guide us to understand this error and overcome this.

Regards
