Dev, with all due respect you seem to be rather disengaged from your project. There have been ongoing problems for more than a day now, yet all we have from you is one post 12 hours ago (and more than 12 hours AFTER the blockchain got stuck) saying that the pool operators need to restart / resync, and the code needs fixing.
I have to agree. What I can share from the mine77 pool server logs is that people are mining blocks, but then the iridiumd daemon is rejecting them. It seems very similar to what is reported
here from another CryptoNote coin, as the sequence of messages in my daemon log are the same (too-big-block, then repeated block not accepted due to bad tx).

etc.
Blobsize from transactions exceeding limit.
