Redis disconnecting and reconnecting on Twisted periodically

I have Twisted server with constant connection to Redis. I'm using library https://github.com/fiorix/txredisapi.

Problem is that from time to time Twisted lose connection to Redis and reconnects shortly after. I have no idea why. Same thing is happening both on my local machine and on my online VPS.

Log:

It happens all day and all night, my logs are getting big quickly.

Log when someone connects while redis is disconnected:

Ok, I got answer from creator of txredisapi. In config there is timeout setting which by default is set to 300 seconds. So simple.
