-Subject: [PATCH] Increase tcp_retries2 value
-
-Current value of 5 results in socket operation timeout after ~12.9
-seconds. This is a bit too low, e.g. we've seen RabbitMQ network
-splits in production.
-
-This 12.9s amount is equal as 0.2*(2^1+2^2+..2^5), where 0.2 is a
-retry timeout (RTO) that is calculated by kernel on a per-socket
-basis. But in fast local networks it usually almost equal to minimum
-values of 0.2s hardcoded in linux kernel (and BTW, RFC says that
-minimum value should be 1s).
-
-On the other hand, comment in netconfig.pp says that our target
-timeout is ~54 seconds. And changing tcp_retries2 to 7 is consistent
-with that comment - tests an live env show that resulting timeout is
-~52.2s
