There seems to be a problem with some transactions on the blockchain.  The following transaction:

3c29b4f814c782e5be30f73b380b8f45bcd1b1d7523ee8291ad4c239a8deb651

Have 0 confirmations after over 9 hours.  There is transactions made after this one that have hundreds of confirmations. Browsing the block explorer I saw a lot of old transactions that also have 0 confirmation.

What happen with these trx and will they be processed eventually?
