Was the command executed at the time, when the pages do not load? According to your log entries, the webshield was out of file descriptors, but according to this lsof output, the webshield has only a few file descriptors open…
By the way, from the lsof output one can see, that you use the avast! mailshield but do not have SSL disabled in your mail client so the mailshield can not scan your mail traffic (you should get warning popups about this). The correct way is to disable SSL in the mail client and force SSL for that account in the avast! configuration in System Preferences.
