CirrusTraffic duplicate on F5
Hello Dears
when user sending traffic to virtual server the traffic is duplicate and sometime the same record of data is inserted twice a time is there any configration on F5 level that prevent that

it seems client does not receive tcp ack from f5 so client does tcp retransmission.
i see at least 2 probable causes:a. "Acknowledge on Push" is enabled in virtual server's client side tcp profile while server response latency is long.
hence, client does not receive tcp ack because f5 has not received server response to be pushed to client alongside the ack.

i suggest you collect tcpdump in client and f5 to see more details.
MustphaBassimHello Dear and thnx for reply
ok let me disable the acknowledge and test
for network connection it seems stuiable since it's inside our company and minium interface is 1G while the F5 withour servers is 10G- zamroni777
just for info: the client side tcp profile means virtual server's client tcp profile.
