Hi,

I have just added tcpkeepalive parameters in nutcracker.yml file but after run it gives below error.

[2017-02-26 22:42:31.554] nc_util.c:203 setsockopt TCP_KEEPIDLE call error(Invalid argument)
[2017-02-26 22:42:31.554] nc_thread.c:278 set tcpkeepalive on c 63 from pool alpha failed, ignored: Invalid argument

Please give idea to resolve the error.

nutcracker.yml :-

Hi,

I want to understand why for 1 ESTABLISHED connection 4-5 fd's are open.

netstat -an | grep "ESTABLISHED" | grep 42704
tcp 0 0 X.X.X.X:42704 X.X.X.X:6381 ESTABLISHED

lsof | grep "ESTABLISHED" | grep 42704
nutcracke 2238 cache 1031u IPv4 83103254 0t0 TCP itx1SPIP-TwPr:42704->X.X.X.X:6381 (ESTABLISHED)
nutcracke 2238 2239 cache 1031u IPv4 83103254 0t0 TCP itx1SPIP-TwPr:42704->X.X.X.X:6381 (ESTABLISHED)
nutcracke 2238 2240 cache 1031u IPv4 83103254 0t0 TCP itx1SPIP-TwPr:42704->X.X.X.X:6381 (ESTABLISHED)
nutcracke 2238 2241 cache 1031u IPv4 83103254 0t0 TCP itx1SPIP-TwPr:42704->X.X.X.X:6381 (ESTABLISHED)
nutcracke 2238 2242 cache 1031u IPv4 83103254 0t0 TCP itx1SPIP-TwPr:42704->X.X.X.X:6381 (ESTABLISHED)

Due to this connections are restricted and i am facing error "Cannot assign requested address" at certain limit fd's open.

Please suggest the configuration to use persistent connections between redis and twemproxy.
