Odd behavior with miners?

Another miner friend recommend I post on the forum about this behavior.

I have 3 workers, same gear, working perfectly well according to their internal monitors.

I noticed that my second worker wasn't reporting any shares.

I looked for more data, and found the chart image, posted below.

I rebooted the #2 worker to see if that would fix it.
It did! Later I noticed #3 was doing the same thing.

Screen grabs from worker history posted in the link.

Thanks for any tips!

Same issue with all D3's. Had to switch over to another pool.

Oh, you don't say..
I'm new here...this is the only pool I've used. D3??
yes, I'm using port 3333. What are the other options for Scrypt?

i had to switch pools too, i was mining the whole day (no issues 20gh's each of my 6 d3) and had 0 shares.

switched to nicehash, mining good past 4 hours
