Hello, I'm having issues with 4.0.3 and netflow. My previous version (3.4-pre) worked ok. I've tweaked some stuff in globals-defines.h, so MAYBE that's causing it. But, I just built an instance with VERY minor tweaks with the same (similar) results. I'll build one with zero tweaks and see what happens.
Some symptoms: With this version I had a tweak for a catching silent netflow crashes enabled. 2011-05-27T17:22:27.382040-05:00 monpapp1 ntop[16093]: RRD: Cycle 0 ended, 3132 RRDs updated, 0.268 seconds 2011-05-27T17:22:39.373225-05:00 monpapp1 ntop[16093]: **FATAL_ERROR** NETFLOW: caught signal 13 SIGPIPE 2011-05-27T17:22:39.373305-05:00 monpapp1 ntop[16093]: **FATAL_ERROR** NETFLOW: caught signal 2 SIGINT 2011-05-27T17:22:39.373696-05:00 monpapp1 ntop[16093]: **ERROR** NETFLOW: BACKTRACE: backtrace is: 2011-05-27T17:22:39.373736-05:00 monpapp1 ntop[16093]: **ERROR** NETFLOW: BACKTRACE: 1.

This is with very minor tweaks, most notably I increased netflow probe count to 40 as I have several netflow interfaces that receive flows from 35+ devices. Ps and top both show the process running: root 2095 1 9 10:24 ? 00:03:11 ./ntop @./ntop-FieldInet.conf But, not taking any cpu tim and the udp receive queues are maxed out and holding. The flow rate from these exporters is low... Also to note, I was using my prefsCache and rrds from my old version. I will build 4.0.3 with zero tweaks and a new directory structure and gradually add things and see what happens. Any other idea's?
