Comment #23 on issue 3041 by omattos: DNS pre-fetching causes frequent internet loss http://code.google.com/p/chromium/issues/detail?id=3041
Possible cause of this issue: Most consumer routers have a run a DNS forwarder, which forwards DNS requests from all computers on the local LAN to the ISP's designated DNS servers. This forwarder also caches all requests. I have observed that on linux based routers, if lots of DNS requests are made, this cache grows in size, and the device runs out of memory. This triggers the linux OOM killer to kill the DNS forwarder process, and then DNS requests from all clients behind the router fail until the router is power cycled. This gives the impression that the connection is "broken", when in fact the connection is fine, just all DNS requests fail. Another cause is some DNS server software, possibly used by ISP's, has a DNS flood protection feature, which will deny DNS lookups to users who appear to be attacking the server with too many requests. If chrome, plus other applications on the PC and other users on the local network together generate too many requests, it could trigger flood protection. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
