Hopefully it can help..
Set NB_TMPDIR to a location that has enough space. Example using /usr/openv/tmp:
# NB_TMPDIR=/usr/openv/tmp; export NB_TMPDIR
Depending on the shell used, setenv or set may need to be used to set the environmental variables.
*** New logic has been added into 7.5 that will cause the NB_TMPDIR to be honored first, when set in the users environment. See the Related Documents for more information
