After removing some commented lines or adding some empty lines or empty spaces in the file module, the error goes away.



pwd:/etc/raddb/mods-config/files

subnet_policies is the file module which gives this error. below is the diff between the problematic file and working file. Just removed a line.



# wc subnet_policies*

  4438   7982 111085 subnet_policies

  4439   7983 111161 subnet_policies.problem
