What's in your bitcoin.conf ?

Code:

minrelaytxfee=0.0001500
blockmaxsize=919899
blockprioritysize=44308
limitfreerelay=6

I have found valid, tx containing blocks in the past..

Additionally, logs from bitcoind. The time shows in UTC here, would that matter?

Code:

2016-04-15 03:20:49 CreateNewBlock(): total size 919823 txs: 1748 fees: 35821561 sigops 3928
2016-04-15 03:21:04 CreateNewBlock(): total size 919890 txs: 1742 fees: 36105460 sigops 3945

You are sure it's your miner that found the block (I'm not familiar with if that message says you found the block or someone else did)?
There's something screwy going on because your bitcoind is offering transaction based work just before you found the block of 910k Perhaps for whatever reason your p2pool client kept building empty block work indefinitely after the previous block through some bug. Is your p2pool code modified in any way?
