Most of the time the home partition fills because of files that were placed there by administrators. I would take a look in the /home/* directories to look for any large files and then 'rm' them. Many times if you capture tcpdumps or audit the files will be placed here and end up filling the partition.
If you were having Admin Console issues then I would say keep it and contact Support with that file. If you are not having any Admin Console issues then I would feel free to remove it. I believe that will clear up all your space in the /home partition.
