I am running into a bit of a (minor) problem with the accounting on our sun workstations... We have a few users that are running simulations for a long period of time and using up a lot of memory. The accounting structure, acct, defined in /usr/include/sys/acct.h, defines the member "ac_mem" to be a short integer. This is apparently not big enough for the *average* memory used by these procs, 'cause its coming out as a negative number in the accounting records. Or am i doing something wrong? Has anybody seen this before or know of a way to get around the problem? Is it safe to cast the short ac_mem into an unsigned value and get the real number that way? I tried that, but the number looked *real* huge, and i wasn't sure if it was a valid number or not. I suspect that once its turned negative, the whole number will be corrupted. derek -- Derek Terveer det@hawkmoon.MN.ORG || ..!uunet!rosevax!elric!hawkmoon!det w(612)681-6986 h(612)688-0667 "A proper king is crowned" -- Thomas B.
