ocminer - any chance you could give eminer.pl a clue as to how you fixed it? 
Sure, they can message me at any time if they need help.
Unfortunately I'm running heavy modified code of MPOS (the backend) due to security and reliability so my fixes/mods probably won't work out of the box.
The main thing with this coin is the 8 second block time.
Your stratum has to purge its shares for the latest every 10 seconds, otherwise the cron job which searches for blocks misses out the shares which found the block. Next thing is that memcached is very important as these big and multiple flushes make a heavy load on the database. Then, you need to run the cron jobs (findblock.php) at latest every 15 seconds (better 10 seconds but thats huuuuuge load on DB)(almost double block find time) and not every minute, thats too late, it will never catch up with the found blocks.
And last but not least (but probably most important):
Use MariaDB , not Mysql
