Ab-initio was terminated abnormally

Hi Cryosparc,

Recently I tried to run ab-initio on a fairly large particle stack (~3M particles, box size 192) with multiple classes (I tried 4 and 6). Unfortunately, ab-initio always stopped in the middle of running with no error info (just general error info “Job process terminated abnormally”); sometimes even the whole cryosparc stopped responding. My workstation has a 32 cores CPU, 4 2080Ti, and 256 GB RAM. The version of cryosparc is v3.3.1+220215. Does anyone have any suggestions on this? Thank you so much!

Are there additional hints in the job log, which can be displayed with this shell command:
cryosparcm joblog <project_uid> <job_uid>


I am not sure if this is a similar issue but my ab-initio job is also terminating abnormally with 1.2M particles. I am not sure what the error is as I checked in J29 and the file does exist, and I checked for corrupt particles and the job did not find any corrupt particles in the stack. Any guidance on what this error is would be great!
