EMULTIHOP
EMULTIHOP is Solaris errno value 74. Oracle describes a file-path operation whose components would require hopping to multiple remote machines when the filesystem does not permit that traversal. The word hop
here concerns remote-resource pathname handling, not an IP packet's router hop count.
Inspect the pathname and mount topology
Start from the exact pathname used by the failing system call. Resolve which components are local and which are supplied by a mounted or historical remote-file service. A path that crosses from one remote resource into another remote-machine context can violate the filesystem's supported namespace model even though both machines are individually reachable over the network.
Changing TTL, traceroute results, or an Internet routing path does not address the documented errno condition. Instead, identify the remote filesystem implementation and restructure the access so the operation is performed through a directly supported resource path. On old Solaris software, this errno can also be a strong clue that RFS-era pathname semantics or compatibility code are still involved.
