RE: [TCLUG:6265] memory leakage with Apache, Perl CGI, and Samba
I'm not sure of your experience with linux, so I will start at the basics
It is normal for Linux to have no memory free. Linux has an automatic disk
swap system. it uses un-used memory for disk swap.
Mem: 63216K av, 61692K used, 1524K free, 18212K shrd, 29148K buff
Swap: 72256K av, 2888K used, 69368K free 10680K cached
this is a system that has been up for 323 days (output from top) notice that
it uses almost 30MB for buffers.. this is all disk information cached in RAM.
Mem: 127976K av, 124764K used, 3212K free, 36496K shrd, 25572K buff
Swap: 128484K av, 6156K used, 122328K free 47708K cached
this is my system.. up for only one day (damn ICMP bug) I run gnome, netscape,
gimp, xemacs, but I still am using 25MB of ram for disk buffer.
there is no memory leak, it's just wasting ram not doing anything with it.
