xmllint is Killed while formatting huge file

I'm trying to format a XML file (2.6G) using xmllint tool and redirecting the output to a file as: xmllint --format response.xml > formatted.xml When the process gets started it is taking all available memory. The output of: free -m -c 10000 -s 30 Is given below: total used free shared buff/cache available Mem: 15290 92 15111 8 86 14974 Swap: 0 0 0 total used free shared buff/cache available Mem: 15290 92
