sort write failed standard output broken pipe--Linux

I am using following commands in my script:

max_length=`awk '{print length}' $File_Path_Name/$filnm | sort -nr | head -1`;
min_length=`awk '{print length}' $File_Path_Name/$filnm | sort -nr | tail -1`;

where the filenm variable contains the name of the file and File_Path_Name contains the directory path.
While executing this from script I am getting the error

sort: write failed: standard output: Broken pipe

Any suggestions what I am doing wrong?

you don't need to scan the file twice for getting max/min try

$ read max min < <(awk '{print length}' file | sort -nr | sed -n '1p;$p' | paste -s)

or you can avoid sorting as well by calculating max/min within awk

$ awk    '{len=length} 
   NR==1  {max=min=len} 
   max<len{max=len} 
   min>len{min=len} 
   END    {print max, min}' file
