Ok that is strange, im going to be a bit blunt. Making a pool is not really something you should go and do right away in crypto without much experience. You have peoples funds in your control and should really be afraid to have anyones money in your hands if you don't know what you are doing. That being said i think its great to learn somehow.
Second blunt thing to say is when you have any kind of problem you must be ever so specific about everything you can to help us deduct what the problem is or could be.
It is usually different for so many people due to so many different operating systems and memory and cpu and internet
You must come into a forum asking for help saying you have a problem and your specs are
1: operating system (eg ubuntu, derbian, centos, windows) and is it a server or desktop and what version the operating system is
2: how much ram you have
3: what cpu you are using (if you are using linux via ssh then put
cat /proc/cpuinfo | grep -i "model name"
4: is the server a home computer or a proper vps or dedicated server.
I think either a couple things have gone wrong 1 its because of your low hashrate but i'm not convinced of this.
2 because your net is extremely bad
3 you don't have enough ram to run the server and programs so they lag to send data through the internet thus you're getting orphans
It could be so many things we just don't know so start by telling us at least those things first whenever you ask for help anywhere you should always give as much information as you can!
i have no problems helping you.
