Hi abhinay,

 

The issue may be caused by the type of virtual server, in a layer 7 virtual server the F5 reads all the packets because you have an HTTP profile to inject a cookie, so it takes a lot of time and is reset because the TCP profile of the Virtual server has some windows size and other checks controls to avoid an overflow of the VS.

 I recommend you use a Performance (Layer 4) virtual server an try the transmission of the packet again, if you need to insert the cookie I recommend you use a different VS for file transmission only.

 

Hope it works.
