Well, the most limited RAM SBC *I* know of is the Beagleboards: the BeagleboardBlack and Pocket Beagle as 1/2Gig. Early model RPis have 1Gig of RAM. Note: it is possible to include swap space on these machines on their uSD cards (but probably not recomended). Compaired to to typical Intel-ish desktop or laptop, this might seem rather limited. But I am not so sure. Are you running a full desktop environment on the machine? I have run a full but lightweight desktop environment on a Pi2 with 1Gig of RAM. Right now, the Pi2 is a network print server. I regularly send arbitary large print jobs. The 1gig of RAM is more than enough to handle the short term pipelines used by CUPS to print stuff, including PDF => PS conversion as needed. You talk about "long running", but that says nothing about the volumne of output. Long running does not equal high output volume. Here is an option: A cron job that triggers the "long running jobs" to gracefully shutdown and then restarts it. You will get multiple "shortened" emails instead on one ginormous e-mail, Each shortened message will get flushed from memory and land in a E-mail inbox queue file. > > > > -- Robert Heller -- Cell: 413-658-7953 GV: 978-633-5364 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services [email protected] -- Webhosting Services
