ELOOP
Symbolic-link loop or excessive symlink traversal
On Solaris, ELOOP is errno value 90. The base message is Symbolic link loop
, but the useful diagnostic context is narrower than the short message: Solaris exceeded the symbolic-link traversal limit while resolving a path.
Use the Solaris-specific errno table first, then compare with POSIX only for portable behavior. Some Solaris values share names with other UNIX systems but have different numbers or more specific historical meanings.
What to check
- Inspect the complete path, not just the final component.
- Check for symlink cycles introduced by deployment or chroot-style layouts.
- Compare with ENAMETOOLONG when the problem is length rather than traversal count.
