cat: write error: Connection reset by peer

I have created a script to cat the contents of a log file and pipe it to head and tail so I can get specific lines.

When I do this I sometimes randomly get the error

"cat: write error: Connection reset by peer". It is completely sporatic and sometimes it doesnt happen and sometimes it does but it means therefore the output of the script is unreliable.

Here is the code I am using where tmpfile is the name of the file im cat'ing and errorstartline is the line number in the file I want to load into the "line" variable.

line=`cat $TMPFILE | head -$ERRORSTARTLINE | tail -1`

I initially thought this was because the TMPFILE was on another mount so I added some code to cp the file to the same dir as the script and then cat but it made no difference.

Has anyone seen this error or can anyone recommend an alternative way of getting a specified line out of the log file. The log file isnt that large I dont think so not sure why I am seeing this issue.

NAME
gzexe - compress executable files in place SYNOPSIS
gzexe [ name ... ] DESCRIPTION
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a penalty in performance). For example if you execute ``gzexe /bin/cat'' it will create the following two files: -r-xr-xr-x 1 root bin 9644 Feb 11 11:16 /bin/cat -r-xr-xr-x 1 bin bin 24576 Nov 23 13:21 /bin/cat~ /bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file. You can remove /bin/cat~ once you are sure that /bin/cat works properly. This utility is most useful on systems with very small disks. OPTIONS
-d Decompress the given executables instead of compressing them. SEE ALSO
gzip(1), znew(1), zmore(1), zcmp(1), zforce(1) CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep). BUGS
gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases, using chmod or chown. GZEXE(1)
