Hmm.  The SMgrRelation hashtable is local in each backend, so I'm not
sure I believe the correlation to other backends being active, but ...

What I'd suggest doing is changing the elog(ERROR) to elog(PANIC)
(in smgrclose in src/backend/storage/smgr/smgr.c), rebuilding with
--enable-debug if you didn't already, and then getting a debugger
stack trace from the core dump next time it happens.
