I have been noticing that my swap space has been growing slowly but
progressively over the past 58 days or so that my system has been up
(RH6.1, p2-400, 288megs, 64meg swap). Then overnight it went from
14megs of swap use to 31megs (based on top command). I cant think of a
reason for this and my reading on swapon and swapoff in the man pages
were not helpful.
Im concerned the my swap space will eventually be used up not to mention
Im puzzled as to why this is happening. Short of rebooting my system
(which Im very reluctant to do for a number of reasons), is there a way
to forcibly reclaim swap space of find out what the offending processes
are that are using up the swap space?
Im attaching a copy of my top -n1b output in case it might be of help.
Thanks.
