Cufft exception in 3DVA job log


I found many lines of “exception in cufft.Plan.del:” in a log file of a running 3DVA job. It also has one line of “exception in force_free_cufft_plan: ‘NoneType’ object has no attribute ‘handle’”. I’d like to know what kind of problem is going on here.

No other warning or error like line in the log file (I don’t attach it here because it has 87890 lines now. Most of the lines(83339 lines) are “exception in cufft.Plan.del:”.).

I can’t check the progress of the job because I’m facing another problem that the webapp stopped updating (refreshing). The job seems to keep running because it using cpu and gpu resources.

Here is the cryosparcm status output

We get the same repeating error in a log file, but during patch motion correction. The job also failed after processing 1/3 of the movies and i can’t figure out why.

OS is Centos 7.5.1804 and error message pasted below.


[CPU: 955.8 MB] Traceback (most recent call last):

File “cryosparc_worker/cryosparc_compute/jobs/motioncorrection/”, line 402, in
AssertionError: Child process with PID 322657 has terminated unexpectedly!

Update: the job completes fine when dropping to 1 GPU instead of 2. Still get lots of “exception in cufft.Plan.del :” in the log.
