VSZ is the amount of memory that the process has mapped, RSS is what is physically in memory. So parts are being dumped to swap as memory fills up. Freebsd will swap out parts that aren't being used. This is not a bad thing, unless your machine is using swap a lot (run top or systat -vm to see what's happening in real time) - in which case you need to get more ram (or reduce the use of it). However, that looks like a particularly high value for nmbd there. Maybe it's a memory leak (or not) be a memory leak. You could probably get some of your swap back by restarting samba :-) > -----Original Message----- > From: Tim Peters [mailto:tim@lost.net.au] > Sent: Friday, November 29, 2002 3:21 PM > To: Murray Taylor > Cc: freebsd-questions@freebsd.org > Subject: Re: swap constantly 50% used > > > On Fri, Nov 29, 2002 at 03:17:38PM +1100, Murray Taylor wrote: > > What could cause 50% of the swap to be constantly 'in use' ? > > [cut] > > > bcall@flea(~/c-code)ttyp1 > ps ax > > [cut] > > Try "ps axl" which will show more information, such as memory use. -tim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
