Configuration 7i92 and 7i77 - get error

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
here

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

"r" and "t" lower case needs 200V for the drive to turn on
"R" and "S" and "T" need 3X200V for the motor to run and are turned on by a relay, so not required for the drive to turn on.

Currently I'm stuck on broken servodrive.
