dnsCache.db memory resident?

I’ve been looking into some memory issues and I’m wondering if nTop loads dnsCache.db into memory and keeps it there?  If this file is 200MB – will nTop need 200MB of RAM just for this?

 

Sometimes my process gets to over 700MB and sometimes it’s around 400MB.  The number of hosts and connections are “about” the same, and I haven’t changed things suchs as sticky hosts, filters, etc. – actually no other changes other than deleting the dnsCache.db

Limit of 16 netflow sources per netflow "device"

Hi all,

 

I’m running several instances of 3.2.1 (I know, need to upgrade) on FreeBSD 6.0 (I know, need to upgrade…).  One of these instances receives netflow exports from apx. 170 offices around the the US.  The offices are divided into 8 sales regions, and therefore I have 8 netflow devices / interfaces configured on unique udp ports – one for each region.

 

The problem is there appears to be a limit of 16 senders / exporters per netfllow device.    Wait……

 

As I’m writing this I thought I’d check the traffic tables to make sure I wasn’t seeing any traffic from the “missing” networks.  Sure enough, they are there!  I haven’t checked for EVERY missing one yet, but so far so good.

 

It appears right now the problem is only in the” Plugins->Netflow->Statistics” page.  In the “Flow Senders” row there are only 16 senders displayed for each netflow device, while some / most of them should have 25 or so each.  I was using this page to reconcile my configs and ensure all my office routers are indeed exporting correctly and nTop sees them.  I guess I’ll have to find a different way to accomplish this.

 

If anyone has any idea’s I’d appreciate it.  Or if I need to document this better for an official “bug” report, let me know.

 

Thanks!

 

Gary
