TCP application logging errors when listen backlog has overflowed

Solution In Progress - Updated -

Issue

  • Abi Nitio application recording numerous "broken pipe" and "flow: Connection timed out" errors
  • Packet tracing shows that after the connection is established the Abi Nitio application sends data which is not acknowledged. It then resets the connection.
  • Packet tracing also shows that the RHEL server continues to respond with SYN-ACK segments, never acknowledging the data from client or even that the client is acknowledging the SYN-ACK response.

Environment

  • Red Hat Enterprise Linux 6.4
    • kernel-2.6.32-358.el6
  • Abi Nitio application
