Lib-CBUS doesn't receive updates

[Nik19792000]

Hi, I've been using Lib-Cbus for several months. Generally it's working great, but I have one consistent issue. Every 1-2 days Lib-Cbus (running as docker container) doesn't receive any notifications anymore about switches turning on/off. Based on debug logs also ping packets are no longer answered. The only workaround is to run a script to check every few minutes to see if any packet was received. If the last packet is more than 5 minutes ago, the script restarts the container. After restart everything works flawlessly again for 1-2 days.
Anyone else faces this issue or has a solution?

Here is a sample log:
