Hello, I am collecting flows using Nprobe v.6.2.1. Before that I was using the nprobe v.5.x and there were no problem with that version in a Debian Lenny box. I upgraded to Debian squeeze and install the Nprobe v.6.2.1. After starting the nprobe after a while (a couple of hours I think) nprobe starts to consume too much cpu. When I look with "top" command the load of the server is about five times more than usual and it stops to collect flows. After restarting nprobe the problem is gone and load returns the normal.
The uname -a output of the server is: Linux xxx 2.6.37.2 #12 SMP Mon Feb 28 09:15:08 EET 2011 x86_64 GNU/Linux An I run the nprobe with /usr/local/bin/nprobe -G -V9 -n x.x.x.x:xx -a -i vlan11 -w 16777216 -I CAMPUS -A /usr/src/nprobe_6.2.1_030511/GeoIPASNum.dat What may be the problem?
