Did you check whether your address received that transaction or not? Use Blocktrail.com, btc.blockr.io and Blockchain.info and see if that transaction shows up.

Here's an audio clip that might be of use to anyone reading this thread.

Andreas A. discusses the three ways to change a too-low-fee TX

• Wait & Resend - Discussed above in this thread
• Replace By Fee (RBF) - Patch available to recompile Bitcoin-QT with RBF support.  Mining pool support is unknown (by me)
• Child Pays for Parent (CPFP) - Already implemented in Android Wallet and Eligius mining pool

I have a Cryptsy BTC withdrawal that has been either not showing or showing Unconfirmed for 3 days

The fee was lower than I would normally set but in this case I used a free w/d coupon so it was set by the sender 226 bytes / fee 0.00002363 BTC

Blockchain never recorded the transaction giving this message “Transaction rejected by our node. Reason: Unable To find all tx inputs”

Blockr did originally show it as Unconfirmed for a couple of days but now doesn’t show it at all

Blocktrail still shows it as Unconfirmed - https://www.blocktrail.com/BTC/tx/cf9e13855beae75131101f201d33ba946cbe2afe009e4bf8dd702e763dd45e58

Does the fact that it still shows at blocktrail mean it might be processed within the 5 day waiting time recommended at the beginning of this thread or am I wasting my time waiting any longer and should request a resend now

And would the fact that it is still showing as Unconfirmed at blocktrail make a resend any more complicated and if so how long might it take for blocktrail to not show it?

Thanks

Wait, you might want to consider paying a higher fee in the future. There are many transactions currently waiting for a confirmation, once those paying a higher fee per byte are confirmed yours will get a confirmation.

[tazdas]

Many thanks for the advice

Ok so looks like both of my transactions in questioin here now have confirmations .

Should be all ok now

[darkstarzz69]

Wow! Thanks for this guide! I finally understand why my smaller transactions take much longer to confirm

[dk8218]

I also suggest you to delay your deal until transaction gets confirmed..
And wait for few days more..
Sometime it happens when there are too many blocks or depends upon transaction fees..
So wait otherwise it will be double spending for sender...

Thankyou

I have an unconfirmed transaction and/or it is confirming super slow. What should I do?Be patient and wait. The transaction should confirm within 5 days. If it does not, tell the sender to resend with a fee. Do not ship goods without at least 1 confirmation. Please do not ask for help; it will not speed up confirmations.


Blockchain.info says it should be confirmed by now, but it is still not confirmed!Blockchain.info's confirmation time is just a guess. Confirmation times may vary wildly, so do not be concerned when your confirmation time is long. Sit tight and your transaction will confirm.


How can I speed up confirmation in the future?Get the sender to pay at least 0.0001 BTC per kB in transaction fees.


How does Bitcoin's fee policy work?Transaction fees are based on the size of the transaction. Sending to many recipients, or sending from a wallet that received "dust" transactions will increase transaction size. How much fee you pay matters as well; 0.001 btc/kb will confirm within the next block whereas 0.0001 may take several blocks. These policies are in place to prevent large blocks (bad for miners) and transaction spam (bad for everyone running a full node).


How do I resend a transaction?Bitcoin-qt will rebroadcast unconfirmed transactions every 30 minutes or so. As long as the sender has his client open, the transaction will be rebroadcast.


How do I resend a transaction with extra fee?Bitcoin-qt users:

• Delete the transaction from your wallet
• Wait 48-72 hours so the network can "forget" the transaction (this step is very important!)
• Send the coins again with a fee

Third party client users


How do I remove an unconfirmed transaction?If you do not want to see the unconfirmed transaction, you can remove the transaction from your wallet. Once the transaction gets confirmed, it will reappear in your wallet.

Its long confirmed[1], contact "support" if the ponzi you send coins to has something like that, if not consider it a lesson for the future.

I set up a simple form to (re)broadcast bitcoin transactions using either the txid, or raw transaction

I heard this might help, but I make no guarantees

[jkminkov]

it was working well until you put that - 66: Mempool Min Fee Not Met

Hmm, yeah... the thing about that...

If there are too many pending transactions, you get that error when your transaction does not make the cut...

Basically, there are 18,000 people in line who are willing to pay a higher fee than you

I set the mempool to 500MB (default is 300MB), but there are currently over 18,000 unconfirmed transactions... cumulative fees for unconfirmed transactions are up to 1,282.62774345 BTC! (an average of 0.071 BTC fee per transaction?!?)

Since you are talking about BITFactory and assuming you are talking about blockchain.INFO (vs some other blockchain service or the blockchain),  you should talk to BITFactory technical support.   If you tried to withdraw from them, did they give you a transaction ID?

You also might try asking in the correct thread.

my node behaves strange, after mem usage on mempool gets close to 300Mb suddenly all inputs get lowest priority enforcing higher than usual fees, all gets back to normal with restarting daemon every 2 days

AFAIK thats normal with 0.12 (core, not sure about classic) as 300 MB is the default limit where the node will drop TX from memory and raise the minrelayfee. This would also affect its feeestimate.
