Re: FreeBSD and DSL CONNECTIVITY ISSUES,

 To All, 
  
 We are running a server using FreeBSD and have been 
 experiencing DSL connectivity issues from our customers. 
 Our pages are basically all HTML and some Java applets. 
 Customers are reporting issues such as; 
  
 Recently I've noticed that your site operates very slowly.  When I am 
 surfing at , the speed gradually decreases until it won't navigate at
all 
 anymore.  sometimes  even breaks my dsl connection somehow and I have 
 to re-start my computer.  One one occasion it actually crashed my machine 
 and caused it to re-boot.  These issues are not occurring when visiting
other 
 websites.  Any ideas? 
  
 Does anyone have any further thoughts on this issue? 
 
Any information in the log files? You could enable PPP logging (see ppp
manpage if you 
are actually using it). Did you control the serverload and/or networkload?
Tools such 
as KDE's ksysguard(d) or gkrellm could help you. They are available from the
ports. 
Also, please supply version-info. 
 
If you are very new to FreeBSD you might want to check the handbook at 
http://www.freebsd.org/handbook/.

There's really not much advice that anyone can give you without
considerably more information.

I don't know why you've obfuscated the URL in question, as that
URL would allow people to test the situation and (possible) give
you the exact reason for the problem.  If you have some legit
reason for not telling this list the URL, you're going to have
to provide a LOT of information, as well as tcpdumps of sessions,
etc...

I can tell you one thing ... it's not possible for your web server
to cause anyone's computer to reboot.  If this is really happening,
then the coputer that's rebooting is so broken that it would be
pretty silly to blame the problem on your web site.

My guess is your Java code has something in it which causes some VMs to
degenerate into badness. This is not to say your Java code has bugs, but
many VMs do. I can't see how your server would be involved in this sort of
problem. I'd gather data on the VMs installed on the machines of the folks
who complain.

One option is to force the VM used by using the Sun Java plug-in.  It supports all of 
the popular platforms.  This helps in getting
most of your users on the *same page*.

I should clarify. People I've talked to who've worked on Java VMs say they
get a bad rap. They blame the perception of applets as being unstable on
browser developers, who supposedly do a bad job of hosting applets. I have
no idea whose side to take on that issue, but gather data on which browsers
are causing trouble as well and you may learn something.

Another thing to look at since it seems that the problem is isolated to DSL
clients is how those clients are connecting to DSL. If most of them are
using a USB-to-DSL device, consider whether their driver is having a bad
interaction with Java, etc.
