UDP unable to send Large data split to packets

[Altris]

HI Im trying to send large data over UDP, since UDP cant send data more than 500 bytes, im splitting data to packs of 500 bytes and sending the pack information initially and reading complete data.

it works great for me up to 64000 bytes or 8000 samples (Double) but beyond that its not getting processed. can some one help me on that 

Im uploading my project here

It would be great if you can comment on the approach i had took  to send comparatively large data

Bit more clarification, as per Labview UDP write, a single write can have only 8000 bytes, so i chose 500 to be my package size, so im sending packets of 500 in a for loop and still im not able to receive more than 65K bytes of data

I build a better send and rec which can stream heavy data
