Yep, I have this problem as well. I have a pi 2 and an original B model pi running wallets. They both stopped syncing at 11:04:04 AM Mar 27 2015.
Both pis have no errors on SD card and both pis have just over 10 GB remaining space. I see no hardware or other problems on my side that can contribute to this.
Edit to confirm I am stuck at the very same block as what is pictured above.
Possible fork/ Disagreement in the chain?
On two locations I download now the blockchain to see if can move it.
What posibilities are there to solve this?
I have send message to the dev and hope he can solve.
What are other options?
What's the difficulty? Sometimes a big whale staking can push up the difficulty so much it takes ages to find the next block.
No, the block explorer shows the last block's difficulty was 0.031, so it can't be that.
