How to solve the problem with a long websocket response?

Question

Yii

Hello!
The Yii2 project uses https://github.com/consik/yii2-websocket
The socket is started by a service on the server.
After about an hour of work, the connection to the socket becomes extremely long, from 30 seconds or more, and only grows over time until the service is restarted. After reboot - everything is connected instantly.
Google did not give much answers, there are no errors in the console, maybe someone faced a similar problem and knows the solution?
Thanks in advance for your replies! :-)

The first thing I would think about is the increasing number of persistent connections
