From what we can tell there's a uncommon condition on the network (seems to be about 1 in 10 clients), where some databases have became corrupt. Please check your logs for these messages:
--
2015-02-15 17:34:26 ERROR: ReadBlockFromDisk : Deserialize or I/O error - ReadCompactSize() : size too large
OR
2015-02-15 17:34:26 ERROR: ReadBlockFromDisk : Errors in block header
---
If you find entries like that delete ~/.darkcoin/blocks and chainstate, then resync from the bootstrap:
https://github.com/UdjinM6/darkcoin-bootstrap
Thanks
i think the same goes for error messages like these :
"ERROR: ProcessBlock() : CheckBlock FAILED"
and
"ERROR: CheckBlock() : Couldn't find masternode payment or payee"
Its not getting the spork settings that Evan has been broadcasting .. deleting the blocks & chainstate and starting from scratch / resyncing from bootstrap should fix it too.
In the end (once fixed) it should be showing info likes this in your debug.log :

these three introduce the spork settings i think .. but it could also be just one of these spork line you come across
