Stratum connection interrupted

[fish34]

Hello! After applying patch (or it not related to it) monero-project/monero@1b8a68f thereis always messages in pool like miner connected and disconnected and in the miner it's
Stratum connection timed out
Stratum connection interrupted.
And timeot of this message differ from miner to miner. If miner 'big' it it often, and if small its rarely.
Timeaout is default 900sec.
I'v googling this problem and found that

and you wrote zone117x/node-stratum-pool@4a088b1
but this is for another version of pool.
Can you and somthing like? Or there is another decision?
