Looks like an read/write error from your disk. The code is not printing the exact exception so it will be difficult to help you, as it looks a hardware failure and probably hard to replicate in another hardware. Are you using the pre-compiled version or are you compiling it yourself? If yes, please find the attached code in main.cpp

Code:

catch (std::exception &e) {
            LogPrintf("%s() : Deserialize or I/O error caught during load\n",
                   __PRETTY_FUNCTION__);
        }

and change to

Code:

catch (std::exception &e) {
             std::cerr << e.what();
        }

so we can have the exact exception message

I doubt it's a problem specific to me.  Appears many people are having the problem.

The only way to get past this problem is to take out the   'connect=0'  in order to sync past this block via internet syncing.  Once you get past it, you can then close the client, rename bootstrap, and start up again.  People having to close and reopen are getting past the problems by simply closing and restarting the client many times.

As long as I keep  connect=0, I am able to get stuck on the same block every time.   I have saved the block state at this point to be able to easily repeat the problem should another test be requested.

I am using the original pre-compiled version on windows.

All in all, I can duplicate the problem several others are complaining about and appears to be at 1781476.

Also, not a read/write issue.   This is on a laptop with an SSD drive when I started the tests.  It is now on a Windows Server (Raid 60) with 32GB ram.
sha256 checks correctly for both machines.
As long as I don't have the connect=0 in clam.conf and I import, and I keep restarting the client (everytime it stops), I can eventually sync up; however, it appears the fail points are the same each time.

Leaving 'connect=0', I no longer load blocks from the bootstrap.  Now I only see (after restarting the app each time)....

0 blocks load.  Again, if I take out connect=0, then it will error; however, it will start syncing from the internet to get past that point, in which case, I can then stop, rename bootstrap, and continue on again until the next point.

Strange, a block with size larger than 1Mb in the bootstrap file? Is there any way to extract a single block from the bootstrap file to verify this?

Where I can find block explorer with nodes/peers addresses? Or could someone write here some fresh nodes to get wallet syncing faster?

Made a tool to list connected nodes in my client, hope it helps

Hi dooglus, I have a doubt, whats is a block "Generated but not accepted" What does this mean to the clam system/network?. I'm having too much of this blocks in my wallet (W 10). Is this related on the the staking machine hardware, internetconnection or just bad luck?. thank you

The bootstrap file is fine. I recently imported the whole thing. I suspect it's the "vtx.empty()" condition which is true.

It would be interesting to have a copy of the clam folder which reliably causes this error. I don't need the 2GB blk* file - I already have that. And I have the bootstrap.dat too. So just the other files.

Dooglus,

I believe Xploited has a email pending with you in regards to the CLAM update.

I guess it's the same as yours. Other than that I'm guessing we are using incompatible versions of leveldb.

Edit: how does the start of your debug.log look when it's failing? Do you see a different "transaction index version" number?

hm, i've got positive BTC balance on block 300377, but didn't claim any CLAM, is it OK or I should have more than 1 btc on this date?

BTW, uploaded current chain here.

You only need over "dust" to qualify for CLAMS.

You can also check your address risk-free for CLAMS at:  https://freebitcoins.com/clamchecker/dig/  (or on Just-dice)

Compared with other coins, clam's price is relatively stable, it is suitable for long-term investment projects.

 used Bittrex recently, because Poloniex had problems with CLAMs. But you have to convert it first to/from Bitcoin.
