Net results for me...
It works great until block 1781476.  It then runs into an error.
If I had to guess though, I would say this is when the client hits a kind of 2GB windows file limit, an error is flagged and the client then goes into syncing mode instead of importing blocks from the bootstrap.

It could be an issue with 2GB filesize limit I guess, or a signed 32 bit variable in the code perhaps. 2^31 = 2147483648.

I would suggest putting "connect=0" in the clam.conf to stop the client ever going to "live sync".

I eventually synced.   Since I don't use the wallet, I will try a couple of tests.

First, I am using:   v1.4.17

Looking in logs, I see the client reaches 751 Orphan blocks.  It gets a bunch more, but each one is numbered 751.   Basically locks up.

I see others have taken the advice of connect=0      I will run that tonight just as another test / confirmation that it may resolve the issue.  Of course, a client update would be needed to make no connections while it is importing blocks.

Since bootstrapping and syncing are really an annoyance right now, is there any chance to make a checkpoint block with all the balances in the non-empty wallets inside the client and start from there in new releases? It wont have any transactions before that, but it can sync the blocks after the checkpoint block faster and enable the person to do transactions, and do the syncing of older blocks after that without hurry

Finally my wallet synced
But helped only  method, when multiple time I closed client, and after change bootstrap.old to bootstrap , run wallet again.(repeated process 5-8 time per day)

Well, again, it stopped automatically for me at block 1775693

This was a key block number in my prior setup days ago during my posts.   Something is definately wrong.  I could understand the random getting disconnected as maybe internet went down; however, at key block numbers is too coincidental.   This is definately AFTER the 2GB blk file is created.

So, my file is now....

This was a key block number in my prior setup days ago during my posts.   Something is definately wrong.  I could understand the random getting disconnected as maybe internet went down; however, at key block numbers is too coincidental.   This is definately AFTER the 2GB blk file is created.

So, my file is now....

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.

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.

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?

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)
