Resolution: Later
> Allow configuration of thrift socket backlog
> --------------------------------------------
>
> Key: CASSANDRA-1663
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1663
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Dave Revell
> Priority: Minor
>
> It would be nice to allow configuration of the Thrift server socket's listen
> backlog size. The current limit is sometimes reached on my servers. I believe
> Thrift uses the ServerSocket default, which is 50 pending sockets.
> This might be able to merge with CASSANDRA-1405, which also involves thrift
> socket changes.
> When connection volume is high, Cassandra fails to accept some connections
> because the socket listen backlog is full. This happens to about 0.1% of
> connections in my case. System load and IO are very low, so this does not
> seem to be a capacity problem.
> Helpful tip: on my Centos 5 box with kernel 2.6.18, the kernel exposes the
> number of socket listen queue overflows in netstat. You can do e.g.:
> {noformat}
> # netstat -s | grep 'listen queue'
> 123 times the listen queue of a socket overflowed
> {noformat}
