Aligning submodels Error => memory short? for 32GB?

We had the exactly same issue as the topic below.

We use split-merge on datasets of 700 and 200 pics, with aws ec2 instances of c5a.4xlarge 16 vCPU 32GB memory, but still get error of Aligning submodels...Segmentation fault.
And after debug, we also traced to /var/opt/ODM/SuperBuild/src/opensfm/opensfm/large/, line 111, in add_camera_constraints_soft, just as the above issue reported
