F5 LTM sending reset packets to Pool member

F5 LTM has a pool member listening on port 8003 and its mainframe server. Pool member is UP but Mainframe console shows consistently F5 is rejecting the connection ( No issues in accessing the VIP )....

Hi,

If possible perform on BIG-IP:

tmsh reset-stats net rst-cause

watch tmsh show net rst-cause

Then try to initiate connection to VS and observer results of watch command - which reason has counter increase?

What can be seen on client side of VS? Can you perform trace - maybe client connecting to VS is sending RST?
