Solution

In Junos OS import, symlink was changed from /usr/libdata/cscript/import to /usr/libexec/scripts/import , but was backed out later from Junos OS 12.3 release.

If any router first loads any Junos OS image that does not have the reverted changes and then upgrades to any other image that has the reverted changes, it will be still pointing to /usr/libexec/scripts/import .

How to verify

m320-re0> file list /var/db/scripts detail

/var/db/scripts:
total 64
drwxrwS--- 2 root wheel 1024 May 1 04:39 commit/
drwxrwS--- 2 root wheel 20992 May 1 04:39 event/

drwxrwS--- 2 root wheel 512 Dec 13 02:23 lib/

Manually remove import symlink as shown below:

>Start shell
%cd /var/db/scripts
%rm import
%ln -sf /usr/libdata/cscript/import import

Commit your changes.

Make sure you do the same on both routing engines if you see the problem on both routing engines.

If the problem continues, please contact JTAC.
