The limits are based on the number of file descriptors that can be open
at one time (usually small).  One way that I often get around this is
by writting something like this which splits up the input on the field $1 .

sort +0 |
awk '
{
	if (last != $1) {
		if (NR > 0) print "!XYZZY";
		print "cat > " $1 "<<!XYZZY";
		last = $1;
	}
	print;
}
END { if (NR > 0) print "!XYZZY"; }' | /bin/sh
