[SunHELP] Seeking advice on swap space

[Sandwich Maker]

"Currently I have a system with 512MB of RAM and it's drives are configured 
"as seen below.  It's currently configured to have 1GB of swap.
"
"My boss has ordered another 512MB for it.  I am not sure that putting 
"additional RAM in the machine without increasing swap space is a good idea.
"
"The machine is primarily a POP3 mail server and up until recently had no 
"issues, but now it's occasionally running out of swap.  I know that adding 
"physical RAM will aid in keeping it from hitting swap, but I am not sure if 
"a 1:1 ratio of RAM and swap is OK.

it is.  solaris2 [and hpux 10+ btw] will run with -no- swap.  the
install cd runs this way.

sunos4 and the ilk -needed- swap, and got cranky if it wasn't as big
as ram.  the standard recommendation was 2.5x, but i used to give it
4x usually.

"The swap issue didn't start happening until I upgraded virus software that 
"is running on the server, so I suspect that there is an issue there.  The 
"additional RAM is a Band Aid.

i think it is time to increase your swap.  if you're running out, you
need more.  as you say, the ram is a band-aid, albeit a generous one.
