Gentlemen,
Actually, I'm pretty sure there are some ladies on the list too :-)
I was trying to open a 200MB .pcap file into Wireshark(1.2.2) under
Ubuntu(see System Monitor.png) and I got the OutOfMemory message.
According to the System Monitor, I was not out of memory(see
OutOfMemory.png).  I have read the Wiki page and it said that it would use
all available memory/swap space.
Is there some setting that I need to set to force it to use all memory
and/or swap space?
Any other reason that it is not using all the memory?
How much memory was Wireshark using when it died?  Is it a 32- or 64-bit 
executable?  (If you're not sure, run 'file' on the Wireshark 
executable, e.g., "file /usr/bin/wireshark".)
32-bit processes will be limited to 4 Gbytes of memory.  I'll look to 
see if that can be mentioned somewhere on the OutOfMemory wiki page.
