what is sufficient free memory?
I had problems with the RAM (128MB SDRAM DIMM) of my server and the only
spare I had was (64MB SDRAM DIMM).
Hear is what top says:
70 processes: 69 sleeping, 1 running, 0 zombie, 0 stopped
CPU states: 0.1% user, 0.7% system, 0.0% nice, 99.0% idle
Mem: 63124K av, 61296K used, 1828K free, 36880K shrd, 7712K buff
Swap: 104380K av, 3128K used, 101252K free 35860K
I'm a little worried that the harddisk might thrash as there's hardly
any more memory to spare (1828K free). This server is pretty much an
"all-in-one" box running DNS, squid, postfix, apache and radius (I have
17 modems on it's cyclades). Any recommendations on the "bare-minimum"
RAM for this configuration? The suits at our purchasing division are
"stiff" at best so when I make the requesition for the replacement, I
need to know if I need to "demand" that they "immediately" cough-up the
128mb (or more).
Thanks in advance,
