Solved: Bandwidthd core dump
-
I see you use (or have used) ntop. How does it compare to bandwidthd?
-
Ntop is beyond basic, It charts everything. I have only checked it a few times as I have had little time to study up on it and all it's functions. I like B d for it's easy to read graphs and counter. And it's got just and only what I want to see at the top of the page.
-
I changed a few settings for the config of Bwd. Then from the console,shelled out and did a chmod 666 (was 600)for the bandwidthd.core file in
/usr/local/bandwidthd and so far no core dumps. It is not quite past the five hour max we have seen. But I usually get core dumps within 1 to 2 hours.
Here's the settings:skip interval=6 (default)
graph cutoff=1024 (default is 100)
prom. on=checked
output_cdf =unchecked
recover_cdf=unchecked
filter=no entry/blank/empty
Draw Graphs = checked
meta refresh = 333 (default is 150):o

Setting the graph cut off too 100 stopped the core dumps. I have ran this on 4 different box's now and all but this machine I set the cut off to 5 ( Make it work + More accurate I figure). First time I have see this issue caused from the cut off setting. It's a 3 Gig cpu with 1 Gb of memory using 14 % at the most. I'm going to try 50 this morning and let it run all day.
Will report back if it starts dumping again. -
;D
Good news. My core dumps are gone too. On the graph cutoff setting….How low can we go!?!
I have dual XEON 2.4 and 2GB RAM using 4 Intel 82558 Pro/100 NICs

I set the problem box to 50 for the cut off this morning and it has not core dumped all day. Will try 25 tomorrow morning. My dell 280 is set @ 5 and has been for months. I wonder if the built in Nic on the IBM is the fault. Both have the same Gigabit dual lan card for the Lan and Opt1 interface. Should have bought 2 of those dells!!
-
The lower the beter. I'll keep bumping my ol' dell 2650 down and keep posting. Also saw in the expired bounty posts references to NIC sensitivity. I don't use the onboard nics on the 2650. Went with two dual intel pro 100s. What's the CPU/ram in the 280?
-
I tried 25 and had an instant core dump So I tried 40 and it dumped again . Will leave it at 50 I guess.
The 280 is a 3.2 and has 2 Gb of memory in it.
It's also running Lusca cache. And at the moment Ntop as well .And the new country Block package. Reporting 49 % memory used.
Really impressed with that box. -
I have one at 20 and the other at 40. So far (3 hrs) and no dumps…....yet
-
I have them both at 40 (plenty low enough) and no dumps. Hope this helps others
