Misbehaving timeout for door closure?

Consider this log:

18:40:34: (309) Mailbox 1 door opened; battery 9%
18:40:35: Mailbox 1 door closure event timed out; potentially lost 1 message
18:40:39: Message counter is out of sync; resetting
18:40:39: (310) Mailbox 1 closed after 5 seconds; battery 9%
18:41:20: Alarm "Door flipped" of mailbox 1 acknowledged via Telegram by Denis 

The timer for door closure on the receiver side is 35 seconds; here it seems to kick in after 1 second only. It is not clear what could cause this apart from yet unknown bugs in DS timers implementation. To monitor.

Also the message counter desync looks suspicious. Actually, there was no desync; but because of this glitch the uptime of the module has been reset.
