I'm glad the issue was raised when it was. It reminded me that I had similar 
concerns about the TS-7250 and writing to a file every 2 seconds for anywhere 
from 45 minutes to 6 hours during a data collection cycle.

An internet search turned up a message thread on this mailing list from 
October of 2005 with the subject line "How to use tmpfs on TS-Linux?".

I was able to mount ramfs with a 1M file size limit. This should be enough to 
handle a 12 hour run cycle (twice the longest expected), and still allow about 
0.5 to 1Meg of RAM to still be free at peak usage when ghostscript is 
processing a .ps file for printing and PDF file generation.
