Can we forcibly close TCP connections in FIN_WAIT2 state?

Solution Verified - Updated -

Issue

  • Is there a way to force the closure of FIN_WAIT_2 sockets left around for a long time?
  • When the application stack is large, if any 3rd party applications trigger this kind of situation of accumulating FIN_WAIT_2 sockets, how can we deal with it promptly without the need to restart the application?

Environment
