How can I increase the TCP listen backlog value of a socket when the application has a hardcoded value?

Solution Unverified - Updated -


  • The application has a hard coded value for the listen backlog that cannot be changed via its configuration file
  • We need the value to be larger
  • Application changes will take too long


  • Red Hat Enterprise Linux 7
  • TCP application with hard-coded listen() backlog parameter
