Crashes Router #94

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. Run App

What is the expected output? What do you see instead?
HTML results page - Error "Non of name servers are healthy"

What version of the product are you using? On what operating system?
Win XP

Please provide any additional information below.

The test start to run fine, but at some point the internet connection is
lost resulting in the error message.

Watching the router carefully it seems that part way though checking the
3400+ servers, the connection is lost.

I did manage to run the test once through sucsfully but never since

What model of router is it?

The only person who can really fix this problem is your router manufacturer. I 
would suggest that you make 
sure you have the latest firmware, and file a support request with them. If 
they don't fix it, buy a new router, 
because who knows when else it will crash.

My only theory as to why it may be crashing is due to the number of UDP 
sessions that it may be handling 
simultaneously. namebench at an absolute maximum is sending 45 UDP packets at 
the same time, which 
really is not a great deal.  It only does so when it is checking the 3400+ 
servers.

Once the first test completes, namebench *should* cache the results of the 3400 
servers, and slow down to a 
more mild maximum of 30 UDP packets at a time to check the best 22 servers from 
that listing. You could in 
theory download the source code and adjust namebench.cfg to use less than 45 
threads, but the initial health 
check will run a bit more slowly.

I'd be curious to hear how this goes for you.
