Hello,
TCP RST from remote system:
When a host (client or server) sends a TCP RST for an existing TCP connection, the BIG-IP system in turns sends a TCP RST to the host at the other end of the TCP connection.
So I suppose that your backend server (Pool Member) send a reset first.

You alwayse receive a reset or sometimes?

if the application layer is http/s then enable oneconnect in virtual server config (if haven't) to reduce number of tcp connection to servers.
and is snat enabled?
