How to fix "Queue is not empty after probing"

да пожалуйста.
According to my observations, the queue error simply replaced the error  Probe tripped during non-probe move.

could you run
latency-histogram
instead of latency-test?
I think you might be onto something, I use a custom version with probe tripped during non-probe move disabled, and I never see queue error...

I just checked master has new option for

[TRAJ]
NO_PROBE_JOG_ERROR = 1

in the .ini file, you could use that to check if the issue goes away?

you have to make sure your version supports this, it's just been added 4 months ago

This feels like possibly a race condition, I wonder what happens if the queue-empty check is just disabled?
(ie, I wonder if it indicates a real problem?)

could you test this?

I guess tomorrow I’ll reboot the machine’s computer to version 2.9.8, reinstall the real-time kernel, and apply all the updates—but won’t that be version 2.9.x? And I’m ready to try running the cycle. If you could provide a link to the 2.9.x build for the real-time kernel (or userspace), I’ll be able to test it.
