Record count problem using sed command

Hi,

I have a script which removes 2 header records and 1 trailer record in a list of files. The commands doing the actions are
sed '1,2d' $file > tempfile1.dat
sed '$d' < tempfile1.dat > $output.txt
Its working fine for all records except a file having size=1445509814 and number of records=13152342. The output has only 5297671 records instead of being just 3 less than the original count.
Is there any limitation on the number of records that the sed command can process?
Some details-
>uname -a
SunOS xx 5.10 SunOS_Development sun4u sparc SUNW,Sun-Fire

>df -k .
Filesystem kbytes used avail capacity Mounted on
xx 67091946 64377506 2043521 97% xx

>df -k /tmp
Filesystem kbytes used avail capacity Mounted on
swap 17337536 1504840 15832696 9% xx
