Someone will know how to maintain a fixed stratum difficulty in the pool, rises dramatically preventing receiving "accepted actions"?
or is it natural?
In my pool (
https://monerolite.superpools.net ) you only have to add a desired .diff after your wallet address.
Now I check the configuration, which may have very high values for this difficulty.

If you have little hashrate in a pool with a lot of people I also prefer to keep the difficulty fixed.
