Try increasing the limits :

echo 8388608 > /proc/sys/net/core/wmem_max
echo 8388608 > /proc/sys/net/core/rmem_max
echo "4096 87380 4194304" > /proc/sys/net/ipv4/tcp_rmem
echo "4096 65536 4194304" > /proc/sys/net/ipv4/tcp_wmem
echo 32768 > /proc/sys/net/ipv4/neigh/default/gc_thresh3
echo 4096 > /proc/sys/net/ipv4/neigh/default/gc_thresh2
echo 1024 > /proc/sys/net/ipv4/neigh/default/gc_thresh1

I have Nessus 3[1] running on FC4 (all the latest updates). I am trying to
scan
an entire /16 via crontab. Crontab issues the following cmd:
/opt/nessus/bin/nessus -T xml -q localhost 1241 myusername mypassword
target-file output-file

The scan gets about 7 /24s in to the /16, then quits. So, if my netblock
is
10.1/16, it gets to 10.1.7. Any help would be mucho appreciated. Cheers.
