Re: [ANN][POOL] Profit switching pool

I have also observed the same behavior on 3 machines, and I have been collecting logs of GPU utilization through nvidia-smi which correlate to the cudaminer log I'm also keeping. I ran cudaminer with "-P" so I've also got a lot of the network protocol. I captured this happening probably ten times last night. It occurs on machines that are also connected to different stratum endpoints. So it's not just an issue with useast, or uswest, for example.

I should also add that the observed idle periods are occasionally quite long, often 15 to 20 seconds. This seems like a very long time to me. When it occurs, no timeouts or errors are printed by cudaminer, so from its point of view there is no problem. This behavior began when wafflepool switched to the new stratum code the other day. Prior to that, I never observed this behavior before.

Any chance you have the protocol dump around when they're idling? Might let me know whats being sent/not being sent during that time...

Yes, I have been logging both the protocol and the GPU utilization for the last 12 hours or so, so I should have several examples of where this occurs in my log.
Right now I see it happening again at about 1:40pm central time...idle for about 1 minute and 45 seconds before it recovered. No errors from cudaminer when it happens, but no activity either. Same cudaminer binary worked fine for the last 2-3 weeks before the stratum change. I can send you a PM with a gzipped copy of the logs if you like. I sent you a short log snippet already last night, but sending the whole log may be more useful for you.

If you can, email me the relevant part (maybe the last 3-4 messages from the server before idle, and the 3-4 messages when idling stops).

Just sent you a relevant section of my log for one of these cases that occured at 13:40pm central time today. I can also send you full logs if that isn't enough. I emailed it to your gmail address.
