DFS Cache Errors

We are experiencing a number of errors on our eZ Publish site with the cache. We have the site set up using the DFS cache mechanism.

The error related to cache we see in the error logs is:

Failed copying DFS://var/luxgoddess/cache/wildcard/wildcard_1341d3207fc33ab8cad27ccc0029fcef_index.php to FS://var/luxgoddess/cache/wildcard/wildcard_1341d3207fc33ab8cad27ccc0029fcef_index1800tmp.php [ Sep 30 2010 20:29:37 ] [69.22.167.118] eZURLWildcard::setupMatchCallbacks():Broken wildcard cache index file.Failed copying DFS://var/luxgoddess/cache/wildcard/wildcard_1341d3207fc33ab8cad27ccc0029fcef_index.php to FS://var/luxgoddess/cache/wildcard/wildcard_1341d3207fc33ab8cad27ccc0029fcef_index1800tmp.php [ Sep 30 2010 20:29:37 ] [69.22.167.118] eZURLWildcard::setupMatchCallbacks():Broken wildcard cache index file.

Our site is usually load-balanced on three servers. The first thought we had was that the various servers were trying to write to the cache at the same time (or something similar) so we took two of the servers out of the cluster. We are still seeing the error.

That helps narrow it down a bit but I still do not know where to look next.

The site has been running really well for the past several months and this problem started cropping up this week on Wednesday. At first I thought it was a one-off issue, I cleared the eZ caches and restarted varnish and things were good. They eventually corrupted again leaving us with empty pages (where nothing loads) or blank content pages, where the outer template loads with the correct styling but no internal content is loaded for a given page.

Any ideas where we should start looking?

Have you look at your free space. I don't know how big your site is but we have had similar situation and solved it by optimizing the server and ezpublish logs, errors, warrnings.
