P2Pmining.com is getting the same error, but most all of my users DOA rate as dropped from ~5% to less than 1%.

[forrestv]

I need as many people as possible to upgrade to commit 0dbb9da28511

Windows build: http://u.forre.st/u/olaxgozi/p2pool_win32_0.11.1-34-g0dbb9da.zip

After a while, everyone's mining will begin working again.

[ChanceCoats123]

Upgrading now.

[JayCoin]

p2pmining.com is now upgraded

[echris1]

static page also shows 40% pool stale rate, upgrading now, might want to send out an announcement on that mailing list I get every now and then (forget where that was exactly, some sort of digest)

[ChanceCoats123]

Got that right away.

[forrestv]

Trying a different approach - get commit 68c11d56a46f388 (current master HEAD) instead! It reverts completely to the old behavior and doesn't drop peers.

Windows: http://u.forre.st/u/oirgpput/p2pool_win32_0.11.1-39-g68c11d5.zip

You will get some errors occasionally, but they should only be like:

Code:

2012-05-18 00:52:25.520715 > exceptions.ValueError: unknown share type: 6

[JayCoin]

While I was upgrading I noticed that in bitcoin/networks.py that the SANE_TARGET_RANGE=(2**256//2**32 - 1 , 2**256//2**32 - 1)

I changed it in my code to a little bigger range than that.  Is that to default everyone to difficulty 1 pseudo shares?

[forrestv]

New version! Pull from git or use http://u.forre.st/u/ocpualfo/p2pool_win32_0.11.1-41-g0dbcc28.zip

[forrestv]

JayCoin: I was paranoid about non-difficulty-1 shares possibly triggering bugs in miners, so I fixed the difficulty to 1 (or .9998.., rather, whatever it is)

[forrestv]

Anyone using previously posted versions needs to stop using them.

working fine

What about "desired versions"?
Red is good or blue? I see on graph that after reset I get all red, now some blue is popping in. Same thing in your. Just change to hour.

Got that right away.

I got that too on upgrading.  Looked like there was something wrong with some local shares.  After that it loaded the rest just fine and is now up and running.  Hope it stops the local rejects.

Having a rough time here with p2pool.  I get random communication problems with p2pmining.com, so my local p2pool is my backup.  Was averaging 10% rejects on my local and higher on p2pmining because of the comm problems.

It is now 50/50 new/old versions.

Pool rate: 439GH/s (38% stale) Share difficulty: 655 O_o
Why so much orphans?

[ChanceCoats123]

Just got on the latest version. I went to bed before forrestv put out the "final" patched version so I was on the wrong one all night. Oh well. Only 30% stales. 

Hopefully this latest will be the ticket. I noticed we're already at 471gh for the pool. We've never been this high before. Maybe there was an issue before that was cutting the hashrate.

[Aseras]

yeah always nice to wake up to 80% orphan shares....

so what happened the "killswitch" for the older versions take out the new versions too?
