Brief Description
We think we have seen connections go away, and we think the cause is a really long operation elsewhere that mean that no SQL was run for ages, thus causing the server to hang up the connection.
Severity
Low (as rarely happens)
Solutions
Should we set keepalives & keepalives_idle? It may be on by default, but on a very high default. Maybe we should turn keepalives_idle down?
And maybe keepalives_interval and keepalives_count too - just to make sure we have good values on them, rather than relying on defaults.
