  • The best thing you can do is raise a case with F5 Support.

    However, you should take a look at and turn on rst logging or cpaturing in a PCAP. My own thinking is that there is something on that virtual server which ASM doesn't like, so do a tcpdump for a single user and work out from there which request is causing the RST. A good idea would be to look at the webchat -

      Whether the ASM policy is in Transparent mode or Blocking, when applied to Virtual Server, the connection is reset. The packet captures shows:

      Internal error (ASM requested abort (plugin abort error))]

      tmm1[29648]: 01230140:3: RST sent from *.*.*.*:443 to *.*.*.*:51570,  Internal error (ASM requested abort (plugin abort error))

      However, when I remove the ASM policy from the VS , the service works fine.
