Frequenty mqtt disconnects with new versions

[giedriuslt]

Describe the bug
New firwares disconnects from mqtt very often. It disconnects every hour or sometimes more frequently. Old version from May was running solid with no disconnects. BL602 also seems to be running with no disconnects.

Firmware:

• Version 1.18.20
• Chip/model: BK7231N
• Config

Are you that's all happening on the same device and is related to the firmware? Maybe capacitor degraded over time or something...

Can you narrow down which commit may introduce the problem?

Is it related to BL0937?

Capacitor would not cause disconnect, device is not rebooting itself. Also downgrading fixes the issue.
I'm trying to find the version, there is more stuff published to mqtt lately, I think that might be causing this somehow.
