What does "BUG: scheduling while atomic" mean and how do we get rid of that in ConnectPort LTS 32?

Here's what Syslog reports about that issue which happens on all our ConnectPort LTS 32.

All units have been updated to the latest firmware version.

All ports use the UDP Socket Profile.

Problem initially showed up when all ports were configured at 1800bps. We changed speed for some but the problem remained.

Communication on the network side is done by a software simulator.
