yeah, it should.  i actually sanitized that wrong, the network is 
x.x.x.0 in the ifconfig.  i typed netmask for whatever reason.

at any rate, i think i've fixed it.  eaccelerator (a php accelerator) 
has problems serving pages from the disk cache.  one of the real servers 
had the disk cache enabled, but the other one didn't, which is why it 
was so random.  i disabled the disk cache and everything seems to be 
working now.  strange thing is that the page is generated and delivered, 
but firefox displays a blank page and ie gives the server cannot be 
found error.

I also did a bit more research and the packets dropped by kernel isn't 
really such a bad thing:

(this is the number of packets that were dropped, due to a lack of 
buffer space, by the packet capture mechanism in the OS on which tcpdump 
is running, if the OS reports that information to applications; if not, 
it will be reported as 0).

Thanks.
