socat runs at 100% CPU forever

After the Turris Omnia starts, a socat process runs at 100 % CPU forever, until I kill it.

As a result, the Omnia is hot:

root@turris:~# sensors 
armada_thermal-virtual-0
Adapter: Virtual device
temp1:        +87.0°C  

kill -KILL is necessary to kill the runaway socat process. Temperature then becomes more reasonable.

root@turris:~# sensors 
armada_thermal-virtual-0
Adapter: Virtual device
temp1:        +76.5°C  

I attach a graph of system load after startup (which the drop after I killed the process)

Note it has been reported on the forum https://discourse.labs.nic.cz/t/big-load-socat-stdio-openssl-api-turris-cz-5679/1141 but I do not know of the Omnia developers are reading the forum? Anyway, as of today, the bug is still present.
