Thanks to both Eddy and to Peter, for making me feel a bit better
<smile>.

Interesting to note that free memory went up quite a bit after the
client switched AMD CPUs between two RaQ4s...

Here's an example from about a half-hour ago:

Machine 60:
         total:    used:    free:  shared: buffers:  cached:
 Mem:  529522688 74301440 455221248 76197888  6545408 33390592
 Swap:        0        0        0
 MemTotal:    517112 kB
 MemFree:     444552 kB
 MemShared:    74412 kB
 Buffers:       6392 kB
 Cached:       32608 kB
 SwapTotal:        0 kB
 SwapFree:         0 kB

And from Machine 66:

         total:    used:    free:  shared: buffers:  cached:
 Mem:  529522688 169959424 359563264 151937024 56315904 46854144
 Swap:        0        0        0
 MemTotal:    517112 kB
 MemFree:     351136 kB
 MemShared:   148376 kB
 Buffers:      54996 kB
 Cached:       45756 kB
 SwapTotal:        0 kB
 SwapFree:         0 kB

Peter thought it was unusual to have a SwapTotal of 0... I'd tend to
agree with him.  Those machines are both from one client; here's the
output of my personal system which has only half as much memory:

         total:    used:    free:  shared: buffers:  cached:
 Mem:  263819264 243580928 20238336 257798144 76079104 84361216
 Swap: 134688768   139264 134549504
 MemTotal:    257636 kB
 MemFree:      19764 kB
 MemShared:   251756 kB
 Buffers:      74296 kB
 Cached:       82384 kB
 SwapTotal:   131532 kB
 SwapFree:    131396 kB

Here's another, from a client with a RaQ3 with 512 megs:

         total:    used:    free:  shared: buffers:  cached:
 Mem:  529522688 518848512 10674176 51470336 86278144 389558272
 Swap: 134692864  2166784 132526080
 MemTotal:    517112 kB
 MemFree:      10424 kB
 MemShared:    50264 kB
 Buffers:      84256 kB
 Cached:      380428 kB
 SwapTotal:   131536 kB
 SwapFree:    129420 kB

So I guess everything is more or less as it should be <smile>.

> What is the RaQ doing or not doing?

The RaQ I've identified as "60" is sitting on the Internet and acting as
a secondary DNS server, but it's not actively serving any sites.  The
one identified as "66" is serving sites and DNS.

My RaQ4 above is serving a few static sites and DNS, the client's RaQ3
is serving some fairly active sites, with bulletin boards, etc.

Thanks, guys <smile>.

Have a happy July 4th.  Even if you're not from the U.S.A. and it
doesn't have any special meaning for you <smile>.
