ELNRNG

A link index failed range validation

ELNRNG is Solaris errno 41 and carries the official label Link number out of range. The current errno catalog does not specify a universal current syscall for this condition, and the name is not part of POSIX Issue 8.

The useful information is the rejected identifier class: a link number. ECHRNG describes a channel number, and the adjacent level-state codes describe synchronization, halt, or reset conditions. If a legacy protocol or driver exposes these values, keeping the field names separate can point directly to the malformed request.

Range debugging for ELNRNG

Capture the link number and the table, topology, or configuration that defines valid link identifiers.
Check whether configuration changed while a cached link ID remained in user space or a compatibility component.
Do not assume “link” means a filesystem hard link or network hyperlink; only the originating API can define the object.
