So I've been pool mining ltc for a while with multiple pools and was not seeing more than maybe 1-3% rejections, mostly when a new block hit...
Last couple of days, I can start a cgminer session on either of my rigs (one at 2.7.5, one at 2.6.1) and it chugs along fine for a minute or two... then it starts periodically flailing about with a ton of rejects for "time-too-old" and does that every couple minutes before recovering, resulting in about 30-50% reject rate... (on any pool)
Nothing has changed with my network connection or bandwidth (20mbit down) as far as I can tell. No updates or changes to the mining sofrware, drivers, sdk, etc...
These things are hasing at 100mh/s per card minimum, so I can't see how they'd be taking too long to submit shares...
So, not limited to pool, not limited to cgminer version, not limited to machine, and bandwidth seems to check out. Any suggestions as to why I'm rejecting a ton more?
I would appreciate any constructive input. Thank you. Is my ISP just crap?
