F5 LTM VE 11.4.1 HF5 - File transfers slow and timeouts from node behind f5 to any destination.

When i do a test from the VM (virtual machine ) from behind the F5 i consistantly fail have issues transferring, the speed goes down to 0 kbps and then picks it up again after a short pause and this is repeatedly happening.

if there is no error in log, i think you may have to capture traffic to see what happens.

 tcpdump -nni 0.0:nnn -s0 -w /var/tmp/output.pcap host x.x.x.x and host y.y.y.y -v
x.x.x.x is source ip
y.y.y.y is destination ip
