Hello.

There is a difference between /tmp and /var/tmp as described in hier(7):

/tmp     - Temporary files not guaranteed to be preserved across
           reboots.
/var/tmp - Temporary files guaranteed to be preserved across reboots.

If it doesn't need the files to persist after the system is restarted,
then it shouldn't use /var/tmp. For example, /tmp can be a memory
filesystem (see mdconfig(8)), and in that case it would improve
performance, that wouldn't happen if it's in /var/tmp.

As a workaround you can:

1) Make /tmp be a symlink to /var/tmp.
2) Use mount_nullfs(8) or mount_unionfs(8) to replace/merge the
   contents of /tmp with a directory of a filesystem where you have
   more space (/var or /usr for example).

Best Regards,
Ale
