  that's fine. It's like an image. As large as you make it takes that much of space regardless how much of that is really being used.

  can i delete it? i found this solution... is it working?

  • stop all services which uses /tmp service httpd stop service mysql stop service chkservd stop
  • remove the tmp directory umount -1 / tmp umount -1 /var/tmp rm -fv /usr/tmpDSK
  • recreate and secure /tmp edit /scripts/securetmp and change the $tmpdsksize to your chosen number of bytes (we use 20480000 = 2Gb) /scripts/securetmp answering yes to both questions
  • restart the server reboot

  You can but you will earn like 2GB extra space...is it worth it? and if you have a busy server 2GB might not be enough.
