cgminer u3 memcpy issue

[btcscot]

hey all

after a few days of fighting my u3s to be discovered by cgminer it turns out they only work on version 4.9.2 now but my issue is i get the following errors 1 straight after another.

Code:

pool 0 difficulty changed to 4000.9

err: asked to memcpy 0 bytes from util.c parse_notify():2077

stratum from pool 0 requested work restart

any help would be appreciated thanks

It is actually a harmless warning but is probably due to the way your pool is set up using a zero byte entry in stratum. You can safely ignore it or mine on another pool.
