Set net.core.somaxconn and net.ipv4.tcp_max_syn_backlog to 1024 for Redis TCP (!2707) · Merge requests · GitLab.org / omnibus-gitlab

Stan Hu requested to merge sh-redis-sysctl-settings into master Aug 27, 2018

If these settings are not set properly, a warning is displayed, and connections may be slow to accept:

WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

We now set these sysctl settings automatically to a default 1024 if Redis TCP connections are enabled.

Closes #3749
