FAUCONNE@FRSIM51.BITNET (10/26/89)
Many, many thanks to all of you who answered my question concerning the
failure to start up common Lisp (eho@clarity.Princeton.EDU,
jjd@alexander.bbn.com, dgh@dgh.EBay.Sun.COM, pbg@BROWNCS and probably
more to come). Basically the answer is : increase your swap space, Lisp
won't live in the default of 16 Meg. Reasonable sizes suggested vary
from 32 to 45 Meg.
I've done so and now I've been able to run Lisp, but this raises some
questions : why does SunOS require so much swap space although it most
probably won't have to swap at all (at least as long as the 16 Meg
single user machine runs a single Lisp) ? Is the swap space allocated as
soon as a program requires more virtual memory, just in case it would
have to be swapped/paged out ? I can't believe that. Sounds like much
wasted disk space and not very bright swap space managment...
By the way what's going to happen if more than one process runs Lisp ?
Am I going to need some 30 Meg of swap space *per* Lisp running ?
I'd better order a new disk at once...
