Use lari(1) with no options, just the executable name:

$ lari /usr/local/lib/erlang/erts-5.6.4/bin/beam.smp

This will produce "interesting" information.  We're looking for stuff
like:

[2:0]: PL_ArenaFinish(): /local/tmp/VirtualBox/ROOT/opt/VirtualBox/VBoxXPCOM.so
[2:0]: PL_ArenaFinish(): /usr/lib/mps/amd64/libplds4.so

(I learned this from Rod Evans in the VBox case.)

Oh, run lari on any and all libraries that might get dlopen()ed.

$ lari bld/solaris-5-11-x86_64-threaded-gcc/lib/libcoresrv.so.1.0

The only thing that comes to mind is transient failure to mount
something (which happens in the mirror mount case, where you get EBUSY
when racing to trigger a mirror mount)...  But that doesn't seem
applicable here.
