	Hmmm, don't see this on Suse 10.2 (but on IBM G5 with the pf-ring code
instead of standard pcap) rc.39 has been running for weeks and rc.40 since
last night without problem. If you 

touch .devel
touch .debug
./configure
make clean 
make

in the top argus directory it will compile with debug symbols which will 
get interesting data if you type "where" at the gdb prompt.
