Issue 3041: DNS pre-fetching causes frequent internet loss
http://code.google.com/p/chromium/issues/detail?id=3041

Comment #7 by [EMAIL PROTECTED]:
There are at least two phrases used here to describe a problem.  The  
original poster ( enderecofacildelembrar,) said the connection "was reset,"  
and imre.polik
said the connection "was dropped."  Imre also said that IP based traffic  
(such as skype) continued to be communicated, but DNS lookups were failing.

I think the original post *probably* meant something like "the phone line  
disconnected" or "the router did a reboot."  I believe Imre may have been  
describing
a failure in a router, which was performing DNS.  For example, there might  
be a watchdog that reset the non-responsive DNS resolver process inside the  
router
after some time period.  ...however... the problem may involve the caches  
on the PC where Chromium is running.

For Imre, can you see if the problem is perchance the OS cache, or  
perchance the application cache.  The DNS resolutions are cached separately  
in both places
(with Chromium's current network stack... which will soon change).  To see  
if the problem is in Chromium's application cache, check to see if exiting  
and
restarting Chromium resolves the problem.  If that doesn't resolve the  
problem, check to see if flushing the OS cache via the command "ipconfig  
/dnsflush" has
an impact.  It is also possible that bug  
http://code.google.com/p/chromium/issues/detail?id=3819 is related (as was  
pointed out in that bug)

Although Chromium can potentially perform many prefetches  
(pre-resolutions), it is currently limited to no more than 8 simultaneous  
outstanding requests (from
the prefetcher).  There is some possibility that other navigations might  
instigate some parallel resolutions (such as for background tabs, etc.).   
In general,
the total limit is pretty small, and probably comparable to having several  
users on your LAN.

Please provide more data if possible.

Thanks,

Jim
