That looks like more of a real time issue than a sserial issue
What was the first error?

Starting LinuxCNC from the command line would probably help
when debugging since all the errors will be logged there and can be copy-pasted

Today I've got such error one more time. I attach copy of terminal output in the file.

I increased watchdog parameter to 5000000. I have default SERVO_PERIOD = 1000000
But I got today another trouble. My one servo drive turns off and doesn't give any sign of life.

It's CACR-SR10BE12G-E yaskawa. I found that on back side is apcent cooling fan. I hope it doesn't overheet. It seems that some fuse in control circuits blowup. I took it home in will look tomorrow what inside.
I make refit of old CNC it's on configuration state. It worked 5-10 minutes.

If you get a watchdog bit error like that, it means you have lost communication
for many cycles.

I would take a look at the tmax parameters after an hour or so of operation

halcmd show param *.tmax

Currently I'm stuck on broken servodrive.
I separated topic for this question here
