I dont think that someone from bc.i is reading along here and removing your transactions from their mempool. I suspect that your client is set to pay a too small fee, which causes bc.i to remove it from mempool automatically. Later versions of qt/core have a fee estimate to avoid this. Can you post the raw transaction so we can take a look at it? You get it by entering
getrawtransaction txid
in the console. "txid" beeing a placeholder for your transaction id.
Sorry, too late. I have no copy of the raw transaction anymore -- I remember the default 1 txin, 2 txout script and about 257 bytes from my memory/brain when looking at the above mentioned URL. There I also clicked the button for show/hide-script ). Immediately after I recognized the deletion of the two TAs in the unconfirmed TA-pool listed on blockchain.info (see the above URL), I deleted my current wallet and the last backup wallet and restarted my bitcoin-qt client with a backup wallet from January 2016. From this I send a new transaction which surprisingly was put into the next new block. From my last experiment of yesterday, I have set my default fee to 0.0001 BTC and will reuse this now as my private standard because miners seems no longer to put standard 0-fee transactions (preciser only with very low probability -- I checked for the number of the incorporated 0-fee transactions in the last 24 hours in the blockchain -- even blockchain.info now calculates the median expectation time ONLY for TAs with non-zero fee in their public chart!).
My bitcoin-qt client (version 0.8.6.0 -- unpatched -- the original, has a standard of 0-fee which you may/can change in the configuration menu/popup)
