Perhaps your DNS software also has a memory leak? Anyone know which
software Comcast was using? Should other ISPs be concerned they might
have the same latent problem in their systems?

Comcast said the intermittent but often-severe nighttime outages . which
also occurred April 7, Tuesday and Wednesday across the country and in the
St. Paul area . are related to software malfunctions on company computers
responsible for receiving, interpreting and routing subscribers' Web-site
requests. E-mail also was affected in some cases.
A company spokeswoman wouldn't elaborate on the nature of the software
problems, identifying them only as a "memory leak." But she said steps
meant to end them roughly coincided with Thursday's erratic outage, which
may have been less severe than the earlier ones, and added the fixes will
likely avert future service blackouts of this kind.
