How about breaking the file into multiple small files do the sort and merge them later.
As pointed out the disk is full, check with "du" in UNIX/Linux.
Try Perl/Python to do a intelligent sort, bubble or something (Please note: At this time I am not thinking of the big 'O' or what is efficient. Just giving few ideas.

NAME
sort - sort lines of text files SYNOPSIS
sort [OPTION]... [FILE]... DESCRIPTION
Write sorted concatenation of all FILE(s) to standard output. Mandatory arguments to long options are mandatory for short options too. Ordering options: -b, --ignore-leading-blanks ignore leading blanks -d, --dictionary-order consider only blanks and alphanumeric characters -f, --ignore-case fold lower case to upper case characters -g, --general-numeric-sort compare according to general numerical value -i, --ignore-nonprinting consider only printable characters -M, --month-sort compare (unknown) < `JAN' < ... < `DEC' -n, --numeric-sort compare according to string numerical value -r, --reverse reverse the result of comparisons Other options: -c, --check check whether input is sorted; do not sort -k, --key=POS1[,POS2] start a key at POS1, end it at POS2 (origin 1) -m, --merge merge already sorted files; do not sort -o, --output=FILE write result to FILE instead of standard output -s, --stable stabilize sort by disabling last-resort comparison -S, --buffer-size=SIZE use SIZE for main memory buffer -t, --field-separator=SEP use SEP instead of non-blank to blank transition -T, --temporary-directory=DIR use DIR for temporaries, not $TMPDIR or /tmp; multiple options specify multiple directories -u, --unique with -c, check for strict ordering; without -c, output only the first of an equal run -z, --zero-terminated end lines with 0 byte, not newline --help display this help and exit --version output version information and exit POS is F[.C][OPTS], where F is the field number and C the character position in the field. OPTS is one or more single-letter ordering options, which override global ordering options for that key. If no key is given, use the entire line as the key. SIZE may be followed by the following multiplicative suffixes: % 1% of memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y. With no FILE, or when FILE is -, read standard input. *** WARNING *** The locale specified by the environment affects sort order. Set LC_ALL=C to get the traditional sort order that uses native byte values. AUTHOR
