Fmriprep stalling during multiband fmri processing

I wonder if it would be worthwhile providing a temporary workaround that disables internal parallelization in FixHeaderApplyTransforms - until we figure out the root of the cause.

Hi all,
sorry to resurrect this topic after so long, but I seem to have a similar issue where a cluster node becomes unresponsive after antsApplyTransf.

I was wondering if the recommended solution is still the LegacyMultiProc workaround, or whether the issue was/can be solved in other ways.

I am currently using fmriprep version 20.2.1.
