Is it stratum vardiif ramping up so you are submitting far less shares but same hashrate?
is there a way to tell?

I'm not sure which of slush's stratum code you're using, as stratum is the protocol, not the software, and cgminer implements its own stratum support. If it's slush's stratum proxy, then that doesn't do anything more than mining directly to bitcoind, and bitcoind can't keep up with an avalon mining with cgminer (it bombs beyond about 5GH). If you are using some kind of pool software from slush, then I'm not really familiar with it, but it could just be increasing your share target difficulty, which is what you want it to do.
it's coming from here: https://github.com/generalfault/stratum-mining/blob/master/INSTALLThat's what you want then. The fact that you've submitted 1013 accepted shares in your screenshot and it counts as 39126 DiffA means you can tell you are running vardiff at about diff 40, which is also what you want.

All looks pretty good. My only concern is more about your Avalon itself. It's obviously hot where you are at the moment, as your fans have ramped up to almost the maximum. Due to them including 2 high pressure 38mm fans and 1 regular pressure 25mm fan, when the 38mm fans run at maximum speed, the air pressure is so high in the case that the 25mm fan is blowing but air is actually moving backwards through it. I don't know what the solution there is...

Sigh, also wrong. The absolute values that count here are: Accepted: 39126 Rejected: 789 HW: 406 Discarded is totally meaningless, I wish it wasn't in the display at all. It's a number from when getwork was the protocol in use and means nothing in the local work generation era.

how long does it typically take to be delivered from China to the US? Any feedback would be greatly appreciated! Thanks for time, Brian

I'm not really sure why this happens, but it appears to happen when code outside of cgminer kills it, so I suspect it's because it's not allowing it time to shut down properly and perhaps the API port is still bound to the old zombie process and you're not seeing the new one mining, or the new cgminer process is fighting the old one for access to the device.
But I see only one cgminer process, and unit not mining at this time (I have watt meter ~34W at idle) and GetWorks slowly incresing over time so It's a same process. I see difference in options & 07/02 frimware: 06/07 frimware: --avalon-options 115200:24:10:43:300 (mining) 07/02 frimware: --avalon-options 115200:24:10:38:300 (not mining & zero temps displayed) What timeout value means?

I don't know what the solution there is... what is the max fan speed? 4000? what's a good range for them to be in? which of the 3 fans is the 25 mm? the one closest to the PSU? edit: what's an optimal temp to run at? someone who knows should publish a set of normal or optimum values for all these parameters.

That's unusual. It should work out to 42:300 now. Did you start with a fresh configuration or have you always done "keep settings" from the old firmware?

Yes, I flashed with "keep settings", I will try reflash later today w/o keeping settings.

however, initially it was streaming thru pages of hashes w/o problem but now has slowed to a crawl. some memory buffer or something must be filling up.
Is it possible that your disk is near its capacity because of the huge logfile ?

Hardware error percentage is: 100 * HW / (diff1shares + HW)
Friendly suggestion: Is it possible to add this percentage to the cgminer web page to make it easier for us ?

I think the interface is confusing most of us: to the occasional observer your system has
Accepted: 1013 Not accepted: (Rejected 4 + HW 406 + discarded 64)= 474
so about 31% is lost? :-)
Sigh, also wrong. The absolute values that count here are: Accepted: 39126 Rejected: 789 HW: 406 Again, this proves my point that the way the values are displayed is confusing The occasional observer does not see Accepted: 39126 (He/she sees 1013) Where is that value? You calculate it? Hands up for those that also misread the stats page (and are not afraid to admit it)?

Accepted/Rejected is changed in the current master version for precisely this reason. The web interface, on the other hand, may lag. It's the legacy of constantly shifting changing landscape of bitcoin mining.

3 Questions:
- my cgminer process seems to restart after every 4 hours or so.. must watch longer to see if it happens regulary. could it have something to do with the --avalon-auto, maybee the freq gets to high and it restarts? I am using --avalon-freq 300-340
- As I read I can forget the "discarded" shares, what about the number of "rejected", do I have to set them also in relation to diff1shares or to the accepted?
-Is it save to use --avalon-temp 55 ? the fans are running at about 2700 under that environment conditions atm.

is there a way to tell? Yes, look at the lines with "Checking retarget for...", you'll see that it grows slowing down share submission. spiccioli

I am not blaming you for legacy cruft, don't get me wrong... By the way, for those using the 0519 firmware from Strombom, don't forget that old cgminer pre 3.2 counted errors as hashrate, which affects the calculations. Another thing that confuses people when comparing performance ;-)
