Zigbee Serial Port Error

Since some days I receive the following error every few hours. Every time, a byte is missing (expected 7, received 6, or expected 10, received 9).

I use the Elelabs Zigbee USB stick. All devices seem to work fine. Only few commands are sent - just a on/off command every few hours or days.

Is this a known issue?

Turning on debug logging and posting a sample. may be useful. See the documentation for “when things don’t appear to be working”.
