Any ideas what this could mean? The server is a FC1 with 1Gb of RAM. I
doubt is running out of memory.

This happens every time I do IP/Local/Network Traffic
Map/networkMap.html

I have posted my configuration below.

NOTE: The --w3c flag makes the generated html MORE compatible with the
w3c recommendations, but it in no way addresses all of the compatibility
and markup issues. We would like to make ntop more compatible, but some
basic issues of looking decent on real-world browsers mean it will never
be 100%. If you find any issues, please report them to ntop-dev.

NOTE: 'Queue' time is the elapsed time between the packet arrival
(libpcap) and the gettimeofday() value as the packet starts
processPacket(). For a queued packet, this includes the time in queue. 

'Processing' time is the elapsed time between starting and finishing
processPacket(). Errors and/or unrecognized packets may cause processing
to be abandoned and those packets are not counted in the 'processing'
averages. This means that the 1024 packets for the 'queue' and
'processing' calculations are not necessarily the same physical packets,
and may lead to over estimation of the per-packet 'processing' time.

Small averages are good, especially if the standard deviation is small
(standard deviation is a measurement of the variability of the actual
values around the average). The computations are based only on the most
recent 1024 packets processed.

Maximum ever ignores the first 100 packets for each device - this lets
ntop get over startup agony.

What does this mean? Not much. Still, 1/(queue-average+process-average)
(i.e. 2747.3) gives a very rough indication of the packet per second
rate this instance of ntop can handle.
