Hi, We are having some connectivity issues on our new cluster. One of our deployments. (N)nginx+php-fpm + (1) redis may be out of connections. and im curios if it could be the connection between fpm and redis.

netstat -t | wc -l

(TIME_WAIT conns) (on fpm -> to redis) is showing values between 2k and 4k while

sysctl net.core.somaxconn

shows a value of 4096 On our old cluster anything is fine and works well while only 100 TIME_WAIT connections for the kick from

net.ipv4.tcp_fin_timeout=60

I allready tried to lower fin_timeout to try to proove that the waiting connections are the issue without any success. Rancher is removing

securityContext:
  sysctls:
    - name: net.ipv4.tcp_fin_timeout
      value: "30"

from our yaml.
