Wait a minute: if I got you right, you are decompressing some user data
into tmpfs?
Note that tmpfs grows as much as needed (up to a maximum size if you set
that -- otherwise all available RAM is fair game). Have you set a
maximum size? Here are two examples from my fstab:
tmp /tmp tmpfs size=128M 0 0
vartmp /var/tmp tmpfs size=512M 0 0
(note that I have 2G total ram). That would mean that those filesystems
are allowed to grow *up to* the respectively given sizes, not more.

Just leave the size out. If you still get "No space left on device"
perhaps there's too little RAM? Another possiblity is that you are getting
the error from another file system.
You might check the output of "df" before running your uncompress script
and after?

First we'll havve to understand what's really happening.
