Can't the backend refuse when the limit is approaching?
Who designed this interface?

So it is find_orphans? Fixing stuff there would be a workaround as seen
from this very error occurring everywhere; see google.

So it is in the same are as the memory leak(s)?
These remain unaddressed for years now.

This very problem (find_oprhans related) should be easily fixable when
looking at the source.
Developers know how find_orphans talks to the backend; developers know
how the backend processes stuff there.
Of course we can dig into the issue , pollute the system with
debug-info, but the core issue is clear. It is not a crash but an
unhandled out-of-filehandles type of situation by blindly accepting all
input via the interface that find_orphans uses.

Kind regards,
