hodl.optiminer.pl downThe DB size grew to >4GB which it was not prepared for.

Originally, I set up this mining pool when there was no pool available as due to the forced locking of coins for 1 year. This is no longer true and there are alternative pools again. As I do not have the time that would be required to run and monitor the pool at a professional service level, I do not intend to bring the pool back up.
I will work on restoring the DB and paying out the outstanding balances in the next weeks.
Thanks for all the mining and don't forget to hodl your coins!
