Exception in planner thread with LIP-VM1

[edgetriggered]

Large scans are dying on loaner laptop (labtop3) at 75% point, seemingly caused by CPU frequency throttling having an effect on meeting a task deadline with three second timeout. Smaller test jobs with a few images to stitch run to completion.

dmesg is filled with messages like the following:

[90759.513304] mce: CPU0: Core temperature above threshold, cpu clock throttled (total events = 545405)

Thanks for your report!

1) We can swap out your laptop. That might be the easiest fix here

2) We'll think over potential fixes here. Maybe a config directive that extends timeouts

[JohnDMcMaster]

I've added a new config directive you can add to ~/.pyuscope. Sample entry that increases timeouts from 3 seconds to 30 seconds. Can you pull latest code, add this directive, and let me know if this solves your issue?

NOTE: another memory corruption issue was also identified and fixed.

{
       "timeout_scalar": 10.0,
       "labsmore_stitch": {
...
}

Is this possibly related to the memory leak? That should now be fixed: https://github.com/Labsmore/pyuscope/issues/375
