Give it time.

It appears that your transaction was not broadcast yet for some reason.

Can you provide the transaction ID?

What version of Bitcoin Core are you using?

Do you know for certain if your wallet was fully synchronized before you sent the transaction?

v0.9.1.0-g026a939-beta (64-bit)

it wasn't fully synchronized at the time of sending [about 20 hours behind]

but I waited until it sychronized, still nothing

I believe I recall occasionally having issues with version 0.9.1 failing to broadcast a transaction if it was sent before the wallet had finished synchronizing.

You can either wait for the wallet to eventually re-broadcast the transaction on its own (I have no idea how long that is likely to take), or you can push the transaction on your own.

If you decide to push it on your own, you can do so as follows:

In the "Debug Window" under the "Help" menu, choose "Console".

In the console, enter the following command:

Code:
getrawtransaction 55a7c966561eba10c7d0128fb73f0cac6604c9cce5058a77cb0a8fbe4188ba69

You should receive a response in the console window of a long string of alphanumeric characters (the hex representation of the raw transaction that you are attempting to broadcast).

Copy the raw transaction to your clipboard.

Load up the blockchain.info "Broadcast Transaction" web page (https://blockchain.info/pushtx) in your favorite web browser:
https://blockchain.info/pushtx

Paste your raw transaction from your clipboard into the text box on the web page.

Click the "Submit Transaction" button on the web page to send your transaction to the bitcoin network.

And the transaction does exist on the bitcoin network (https://blockchain.info/tx/55a7c966561eba10c7d0128fb73f0cac6604c9cce5058a77cb0a8fbe4188ba69) now.

Your wallet must have broadcast it while you were waiting.

Unfortunately, you didn't include any transaction fee with the transaction.  As such, you'll have to wait for a generous miner (or mining pool) to confirm your transaction for free before it will show up as confirmed in the blockchain.

Since the transaction has low priority, this could take anywhere from a few minutes to several days.

I am saving these instructions, will definitely see useful for me in the future. Thanks DannyHamilton.
The transaction is confirmed now, I just checked.

You're welcome.

If blockchain.info is down (or if they no longer support that page), you can also push transactions directly to Luke-Jr's pool, Eligius, at the following website:

Yes it is.  And iluvbitcoins should now see it with at least 1 confirmation in his wallet.

Seeing this just drives the importance (imo) for the "Child Pays for Parent" patch.

However, I'd like to know if the issue arose from not including a TXFee, if it was due to not being synchronized, or a combination of the two?

Why?  How would child-pays-for-parent help with a transaction that the network has never seen?

However, I'd like to know if the issue arose from not including a TXFee, if it was due to not being synchronized, or a combination of the two?

I believe it was due to the use of an older version of Bitcoin Core combined with an attempt to send a transaction before the wallet was fully synchronized.

As I said, with that version of bitcoin core I've experienced issues where it does not broadcast a transaction that you try to send before it is fully synchronized.  Therefore, the network doesn't see the tranaction until/unless the wallet re-broadcasts it later.

The lack of a transaction fee was not an issue in this case at all.  The transaction was quickly confirmed once it was broadcast to the network.

I was never sure how the synchronization of the wallet changed outgoing transactions - It's nothing I've ever attempted or looked up.

Makes sense to me now. Appreciate it.

I'm noticing similar.  The site I sent it to shows incoming transaction but Blockchain.info shows nothing.

Blockchain.info has some bugs in their software.  They don't always notice the newest blocks, and can fall several hours behind the actual blockchain.

So far, they've always fixed the symptoms eventually, but at times it can take a day or two.

Contact their support and complain if you have a blockchain.info wallet.  If you are just using their block explorer, then use a different one (such as blockr.io or blockexplorer.com)
