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.

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

Here is the snippet from the debug log.

Although orphan stays at block 0, no more bestchains appear to have loaded. In the end, I see....

So, I made a backup of the debug.log file at this point, renamed the bootstrap.dat.old back and restarted.

Appears to be running like it should......

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
