Yes - I run that way all the time to save RAM, also have decoders disabled. Did u see my later post re SNMP? Commenting that out of the code seems to have done the trick, but I do like SNMP and would like to make use of it if possible.

Avg, load on FreeBSD 6.0 is around .5, CPU around 40%, and udp port queues (netstat –a) are most always zero, but sometimes a couple get a little backed up for a few mins here and there. Now running 3.3.8 compiled from ports. Load now 1.8, CPU 100%, and most all udp netflow queues are maxed and not emptying, especially within one instance that has many flow exporters – about 160’ish: $ netstat -a | grep flow Ntop Instance 1 udp4 41200 0 *.netflow-Regn29 *.* udp4 41496 0 *.netflow-Regn16 *.* udp4 41456 0 *.netflow-Regn15 *.* udp4 40904 0 *.netflow-Regn11 *.* udp4 41544 0 *.netflow-Regn10 *.* udp4 41456 0 *.netflow-Regn02 *.* udp4 41552 0 *.netflow-Regn88 *.* udp4 40656 0 *.netflow-Regn53 *.* Ntop Instance 2 udp4 0 0 *.netflow-Inet *.* Ntop Instance 3 udp4 0 0 *.netflow-LANCore *.* 3.2.1 had its issues, but as far as netflow and cpu load it was fine. I’d like to get on a more recent version, but keep hitting roadblocks. Tried this back with 3.3.1 (I think?) with similar results. Nothing in logs I find interesting. Only interesting thing on compile what something about “sched.h”: checking sys/sched.h presence... yes configure: WARNING: sys/sched.h: present but cannot be compiled configure: WARNING: sys/sched.h: check for missing prerequisite headers? configure: WARNING: sys/sched.h: see the Autoconf documentation configure: WARNING: sys/sched.h: section "Present But Cannot Be Compiled" configure: WARNING: sys/sched.h: proceeding with the preprocessor's result configure: WARNING: sys/sched.h: in the future, the compiler will take precedence I’m willing to do anything reasonable to help get this resolved. Any help would be greatly appreciated!!! TIA! Gary "This email is intended to be reviewed by only the intended recipient and may contain information that is privileged and/or confidential.
