Hi, I made TCPdump on updated unit and it behaves this way:

 

  1. user sends GET request to LB
  2. LB responds with 301 redirect to proper path
  3. user sends new GET request with proper path
  4. LB makes TCP connection to frontend server and sends HTTP Request
  5. LB never get HTTP response only ACK on TCP layer

Pool monitors are UP, no ARP issue as I was wondering. ASM was taken out from VIP and anyway not generating anything strange when it was used.

 

Do you have any clue somebody, or did you experience something like this?

 

Thanks, Zdenek
