Description (partial)

Some FEX modules got disconnected from the parent Nexus 5000 switch during an external file copy to disk. 

When this happens, the VTY session and the file transfer progress hangs as well.

This was observed under the following conditions:
- Nexus 5020 switch with multiple FEX modules connected to it. 
- /var/sysmgr internal directory is at high usage. This can be checked using command:
# show system internal flash
- The file transfer was made via the mgmt0 interface.
