Possible? Yeah sure, I suppose it is "possible". But you'd do better to give us a more systematic profile of what the router is doing if you want good opinions.
The "load average" numbers that various apps report are sort of odd things. They don't represent a true system "load", at least not to my thinking; instead, they represent the average number of processes that are waiting for some resource to be allocated to them (that is, blocked processes). Unless you are running some unusual userspace firewalling app on your system, I wouldn't expect basic routing demands to increase system load by this measure. So ... in your guess, substitute "blocking" for "looping" and you are probably right. But what process? Hmmm ... here are some things to consider (and perhaps tell us about): 1. How does CPU utilization change with this change in load? If you have "top" available, it calculates and reports the numbers I have in mind; if not, you'll need to get the raw data from /proc/stat and do the arithmetic yourself. 2. What userspace apps are you normally running on the system? 3. Does "the dns is no longer reliable" refer to a DNS server on the router, or do you just mean that the slowness of the line causes offsite DNS requests to time out (or do you mean something different from either of these)? 4. What apps does "top" report as high-usage? 5. What filesystem hardware does the router use? (Blocking can easily be due to the need to access a slow hard disk, for example.) In particular, might syslogd be blocking somehow (it is a natural one to think of as creeping up over time)? All of this isn't even up to the level of fishing yet; it is just some preliminary thoughts about a problem on a vaguely described router and network.
