For a site imageocd.com that I just set up I initially spelled the category "automobiles" as "autimobiles"... I know it's rediculous. I then set up over 10,000 pages behind that category e.g. imageocd.com/automobiles/hillman-minx-cabrio-pictures-and-wallpapers.
So, I set up over 10,000 301 url redirects to change the spelling on automobiles. I just checked my Google Webmasters report and got an error saying:
www.imageocd.com/: Googlebot can't access your siteSep 7, 2012
Over the last 24 hours, Googlebot encountered 2 errors while attempting to retrieve DNS information for your site. The overall error rate for DNS queries for your site is 66.7%.
Could the overabundance of 301 redirects be causing this? I host 13 sites on this dedicated server and all sites are running fine. I also contacted GoDaddy and they said the server is running fine. Any ideas on what might be going on?
Also, I have "canonical" set up for every URL. Could this be part of the error? Thanks.

You could maybe consider using phpmyadmin to do a SQL update to the misspelled category in your db? Then no redirect necessary...
DNS errors occur before the server is even hit, so redirects wouldn't affect this. I checked your site on a DNS checker here and didn't see any problems. It was probably just a temporary issue.
There are no problems with the number of redirects, in terms of how many pages redirect to a second page. The only problem occur when you chain redirects, e.g. Page A > B > C > D - Google will usually give up after 4 or 5. But you are not doing this so no need to worry. See this webmaster help video for more information.
There wouldn't be a problem with any number of 301s technically, except for network noise and lag it creates, etc. - plus extra load on the machine.
Googlebot only goes so far before quitting though and just as it would only scrape so far deep into a site, I don't think it would traverse that many 301s. Very likely it would think at a certain point that it was an infinite redirect and quit.
If it's not an option to fix the typo, it would be a better solution to create a symbolic link in the filesystem that sends the traffic over to the other directory. Not sure what os you're running on your server. On linux it's: ln -s target linkname
