MPM export to VDB points crashing under high solver detail size

Exporting MPM sim to VDB using testing detail size of 0.2 and 0.1 I'm able to generate vdb points, using 0.05 that's my target sim resolution Maya crash.

Maya produce a valid first frame 48MB file

and next crash with this error

Same result using Bifrost 2.3.2.0-rc _202111120330_ab29d85

Goes a bit further after first frame, using more RAM (up to 47GB), but in the end crash before producing second frame.

Same crash info, attached report.

is it possible for you to share the scene file?

I like to have a look at this.

Thanks

Sent you the project, in the meantime I tested and the crash happens also using VDB volume and Alembic.

@Aslan.Jafariafter finishing another project I'm re-starting working full steam on this topic.

Wanted to ask if you was able to replicate the problem on your side.
