Stop all processes that have files open on /tmp such as MySQL and other applications using:
 /usr/sbin/lsof /tmp
 Run the following commands (in that order):
 /bin/umount -l /tmp
 /bin/umount -l /var/tmp
 /bin/rm -fv /usr/tmpDSK
 /scripts/securetmp
 This should create a new /tmp partition for you. That's all
