Currently trying Maged's idea of restoring a backup bitcoin folder. Less than 2 days behind, should be up to date soon and know whether I'm all sorted. Smiley

I found the following in your debug.log:

Not sure exactly what that tells us but those are the starting characters of your 5 tx's.

Also found this:

The above actually appears a number of times (so I guess it kept trying to resend these tx's unsuccessfully).

Sorry for the ignorance. This log means nothing to me. Can anyone find anything in here that would tell me what to do?

Note:

I searched for the 5 transactions you reported in the debug.log of my Electrum server  (it is always up).
My server has not seen these transactions; I guess they were not propagated by the network.
It could be a double spend attack, or a problem with the bitcoin client used by your customers.

why don't you ask your angry customers to provide details on the transactions they did?
are they really 5 separate customers?


These are transactions FROM me not TO me. And I am aware from bitcoincharts.com that they are not even on the network as unconfirmed. However, even with a rescan they are no longer showing in my balance.

sorry for the confusion :-)
it looks like they were rejected by the network.
check your own debug.log to see the cause (probably a blockchain reorg).


What should I search for?

search for ERROR.
on Linux, you can use grep :  
Code:
cat debug.log | grep -10 ERROR

you should see lines that look like this:

Code:
ERROR: ConnectInputs() : 6501716a6a mapTransactions prev not found 3ad23a50d9
(with different numbers)

you can also use the first chars of the transaction hashes in the grep command:
 
Code:
cat debug.log | grep -10 ccf585

Well, the easiest solution at this point would be to revert to a recent backup of your wallet (you have one, right?) and double-spend these coins by sending the entire contents of the wallet to another of your addresses.

If I do this will it mess up the 120 or so transactions I've done since the corrupted transactions?

I think the default keypool is only 100.  If you're doing this many transactions you should set the keypool size to 1500 or some other high number so your backups are at least valid for a few days.

Anyway, if over 100 of those transactions are receiving coins to new addresses (this includes any sends with change), you might lose some bitcoins.  Otherwise you should be okay with your backup.  If you've used too many addresses, I'd set up pywallet and remove the transactions from your live wallet after making a backup (without bitcoin running).

Finally, to figure out what went wrong, as ThomasV suggests, check your debug.log.  I imagine yours may be fairly dense if you are doing so many transactions.  Searching for the first 10 digits of the transaction id should get you in the right area.

Maybe you are the victim of a doublespend ?

If the backup contains all the private keys, a rescan should be enough for it to see transactions that were confirmed. It will see them in the chain.
What's important is that the backup contain all private keys, but not all transactions.
Keep a copy of your current wallet before doing this, of course.

Good point. I'll try this. Thanks!

I thought these transactions were initiated by Jeremy's wallet...
If they are incoming transactions then the problem is not with him, but with those trying to send the money.

I have 84 other send transactions that confirmed as normal during the same time period.
this suggests that your client is OK.

if you reload the blockchain from scratch it will interrupt your service, and you'll get more angry customers.

just stop your bitcoind and restart it, and check if these transactions are still displayed by your client;
they might have been rejected by the network (eg double spend)

I've restarted it several times, to no avail.

I use a separate wallet for spend transactions and there will be no buy transactions due for 19 hours now which should be enough time to reload the blockchain, plus I have a backup in case I do need to get in earlier. Smiley

If you do end up deciding you need to reload the blockchain you might also be interested in the following (at least for testing before you end up wasting too much time):

Otherwise, you can set-up pywallet and delete the individual transactions from your wallet. It's easy to do this, luckily, but setup is a pain (lots of sitting and clicking until everything is installed).

Unfortunately these solutions didn't work. I'll be redownloading the blockchain scratch tonight, it seems.

Sorry to hear that - and from a bit of searching it seems that if the issue is actually within your wallet then even reloading the entire blockchain may not fix the problem.

I found the following that might be of help in this case:
