@mpirvu does this file seem familiar to you?

[mpirvu]

These look similar to the hidden files used as a backing for data structures that we want to disclaim. However, java code should not ask about them.

[pshipton]

If it's a hidden file on Linux, I think it needs to start with ..
i.e. .omrvmem_003871063_KBIHTZ

[mpirvu]

On my system those backing files appear as
/opt/IBM/OL-24.0.0.2/liberty/usr/servers/acmeairee8/omrvmem_000219066_Ig4oyo (deleted)

[pshipton]

I guess sometimes they get created in an unexpected place?
