Feathercoin-qt is not synchronizing

[curiosity81]

I also tried to download the whole blockchain again, then, when roughly 19.000 remaining blocks are reached, after some time, it goes quickly down to 500, ends synchronizing, and starts again from 19.000.

Anyone any idea what is going wrong there?

It is a Linux system, and the wallet is compiled from source ...

For people who are faced with the same problem, the solutions is as follows: I downloaded the current source from github and compiled it newly. Now it downloaded the blockchain correctly. Don't ask me what was wrong with the old binary, maybe it was too old (3 month).

I'm having the same issue. I compiled straight from the git repo but it still doesn't sync.

Code:

EXCEPTION: 11DbException       
Db::get: Onvoldoende geheugen beschikbaar       (translation: insufficient memory available)
feathercoin in ProcessMessages()

Sorry, no idea. There was no exception about memory on my system. What system you are using?

There was a hardfork sometimes back.

Indeed. They posted quite a few weeks ago about this issue in their topic. Downloading the newest version (and the whole right blockchain) worked for me.

Edit: check this: https://bitcointalk.org/index.php?topic=300795.msg3225687.

The latest Feathercoin version 0.6.4.4 is now available and is a mandatory update. This update includes a hard fork of the block chain to accommodate the changes made in this patch. This hard fork should happen roughly around the 1st October which is only a week away.  To be able to send and receive Feathercoin after block 87948 you have to use the new client. Continuing to use old clients after the hard fork could result in the loss of coins.

Primarily this update is to further the refine of the difficulty adjust. Though the current Feathercoin difficulty which we changed to get us out of a tough spot it is not fair for long term miners who have to experience 41.4% swings on every adjust. The new code will adjust four times more frequently at 126 blocks but to approximately 9% which still gives the exact same overall adjust. To prevent the difficulty from being sent up or down too rapidly the current 504 sample window is being maintained and damping is being introduced to reduce fluctuations between extremes.

Myeah, redownloading the blockchain worked fine. Thanks

No problem . Glad I could help you. I really like the FTC, as it doesn't have had as much problems as other altcoins. And, they're still quite easy and profitable to mine.
