Resolution

Workaround:
Permission of the file can be changed to 666 (-rw-rw-rw-) to avoid this error.
 
Commands:
>shell
#cd /nsconfig
#chmod 666 .callhome.conf
 
Permanent fix:
We have already developed a fix for this and it will be included in Version 12.0 Build 58.x and later.
 

Problem Cause

File /nsconfig/.callhome.conf is have permissions 644 (-rw-r--r--) and the file is always opened with r+ mode. If the user does not have write permission will get this error.
There is no functionality break due to this.
