We keep getting the following error popping up in the apache error log:
[error] (103)Software caused connection abort: cache: error returned while trying to return disk cached data
This error occurs at irregular intervals, but on average about 1-2 times every 10 minutes. Over the past 2 days the site has gone down several times, possibly because of this error.
The only other error that is popping up in the log is client denied by server configuration
, which has occurred about 10 times over the past 2 days.
We're using Apache/2.2.14 (Ubuntu). Top returns:

Any ideas what might be causing this issue and how we might resolve it?
