RHEL: Why is the kernel ignoring a TCP reset?

Solution In Progress - Updated -

Issue

  • We have a system running 2.6.32-504.23.4.el6.x86_64. On this system a connection to the server is showing up as ESTABLISHED while the server had sent a RST couple of hours back. We wanted to know if there is a known issue due to which the Kernel does not handle RST correctly.

Environment

  • Red Hat Enterprise Linux
    • kernel 2.6.32-504.23.4.el6
  • Oracle Server running AIX 6.1 TL-07 SP-2
