I agree with John's comment.  Realtek chips are junk with unpredictable 
reliability, especially under heavy load.  I have had several problems 
with various versions of the 81xx chips.  When I tossed the cards in the 
garbage and switched to Intel-based NICs, all the problems went away.

Every time I build systems with Realtek network chips on the 
motherboard, I disable them in the BIOS and add Intel NICs instead.

YMMV, but please consider ditching Realtek altogether.
