Mikhail Bautin commented on THRIFT-1653: ---------------------------------------- Dominik, Jake: thank you for your replies. We are using Linux with /proc/sys/net/ipv4/tcp_fin_timeout value of 5 seconds. Is that low enough based on your experience? If there is no bug in TThreadedSelectorServer (we could not find anything obvious by reading the code), then another thing we could try is to reconfigure the application to keep more connections open and create new connections less frequently as a result. > TThreadedSelectorServer leaks CLOSE_WAIT sockets > ------------------------------------------------- > > Key: THRIFT-1653 > URL: https://issues.apache.org/jira/browse/THRIFT-1653 > Project: Thrift > Issue Type: Bug > Reporter: Mikhail Bautin > Assignee: Jake Farrell > Fix For: 0.9 > > > We are using TThreadedSelectorServer in HBase regionserver.
