If that file exists in /tmp, try deleting it. It's also possible that if you have a virtual /tmp partition that it's become corrupt and needs recreating.

hrmm

no file of that type in /tmp and im not sure where a virtual /tmp folder would be hiding?

ive tried to locate the file with no luck

If you run:

df

And see a line similar to (sizes will differ):

/usr/tmpDSK 1007896 18336 938360 2% /tmp

Then you're using a virtual partition (i.e. it's a partition in a file).

You need to stop all the processes with files open in /tmp:

cd /root/
service chkservd stop
service httpd stop
service mysql stop
service postgresql stop
service xinetd stop

Wait a few seconds then:

umount /var/tmp
umount /tmp


If it says it's in use, find out which processes with:

lsof | grep /tmp

Kill them off and then retry the umount.

Once umounted, delete and recreate /tmp:

rm -fv /usr/tmpDSK
/scripts/securetmp


That should be it in most cases.

Oh, restart the stopped processes:

cd /root/
service xinetd start
service postgresql start
service mysql start
service httpd startssl
service chkservd start
