[Solved] v0.8.6.1 stuck at block 33,582 for many

v0.8.6.1 Client will not sync past block 33,582
I have done all the usual tricks to get it moving and all have failed. I have asked my Feathercoin group and everyone that re-installed the client is stuck here as well.
I’ve watched it sync to 33,582 about 15 times on fresh installs/some different machines which takes only a few minutes, but then it immediately throws the following over and over again:
ERROR: AcceptBlock() : block's timestamp is too early ERROR: ProcessBlock() : AcceptBlock FAILED ERROR: ProcessBlock() : CheckBlock FAILED ERROR: CSyncCheckpoint::CheckSignature() : verify signature failed ERROR: CheckProofOfWork() : nBits below minimum work ERROR: CheckBlock() : proof of work failed ERROR: ProcessBlock() : already have block XXX -
Cheers for reporting that. Looks like an early hard fork is causing a problem. That may be due to tightening the block criteria, or some such.
Certainly needs looking at quick. I’ll message Peter he needs to look at it ASAP.

It would help Peter to investigate this - to see the Debug.log entries show any further detail.
Debug is in users appdata in Windows or .feathercoin in Linux.
If any one can have a look, post any relevant messages…

As a workaround:
If you have the .feathercoin directory from the 0.8.6.0 client you can work on this one and get past the problem.
I copied the .feathercoin form my 0.8.6.0 installation to the 0.8.6.1 installation and my client is synced now.
Under Linux the directory is $HOME/.feathercoin and with windows it is user\appdata\roaming\feathercoin or %appdata%\feathercoin

Are you sure that feathercoind need to reinstall ? FTC pool must git and compile code again ?
-
Lizhi, you will need to reinstall, the old client will not work after the Hard Fork.
Wait till we find what this “sync bug” is first, though.

Getting stuck on block 33582
block time: Sat Jun 8 10:15:42 2013
Isn’t that the date there was a 51% attack on feathercoin?
Could that be the cause of getting stuck at that point, or is it just a coincidence?

All sync issue post mopped into support thread here https://forum.feathercoin.com/index.php?/topic/6946-v0861-stuck-at-block-33582-for-many/
I have sent PM’s to users to inform them
UM
Uncle, Thank you for merging posts to my thread

Is it safe to post/attach the entire debug log here or should I PM it to someone?
I upgraded without any problems. Wonder why this happened to so many people… What version of wallet you guys had before this upgrade?
It’s fresh installs mostly - not everyone keeps an up to date chain (cold storage ect)
-
I’ll stand a new machine up tomorrow morning and dump to the debug.log and get it posted.

+1 Same here… Got the solution though :)
It’s a problem in the latest version, changed enum { nMedianTimeSpan=11 }; to enum { nMedianTimeSpan=13 };
and apparently broke it.
Either get the previous version or recompile with that change reversed, until devs fix this.
this guy discovered it today:

Cheers,

I will get on to this now and release an updated version when I have the fix.
-
Apologies for not picking this up sooner. I am away in Germany with my family so am not as on the ball as I normally would be. I have replicated the problem and will now work on the fix.

The problem is what was reported on BitcoinTalk. That makes things a bit quicker to resolve. The change has been put on to GitHub and you can download the latest Windows client from the link below.

I am compiling the Mac client now.

is the move to 0.8.6.2 required?
-
Only if you need to do a full sync of the blockchain. If you already have the blockchain downloaded then you do not need to have this version.

Good work on fast update, will download later get things synced up.
