Hello, I'm using K2 v2.6.7 and XMAP v2.3.4 on a popular site running Joomla 3.2.0 and since migrating from Joomla 2.5.16 to Joomla 3.2.0, Google Webmaster tools has been sending me multiple emails which state:
Increase in server errors
Google detected a significant increase in the number of URLs we could not access. It is likely that your server had an internal error or was busy when attempting to process these requests.

---

Recommended action
Check the Crawl Errors page in Webmaster Tools.
Check your scripts and script permissions.
Examine the log files on the server for your site for scripts or pages that might be crashing.
Consider addressing the load on your server.

The crawl errors seem to be K2 related. I've confirmed this with server engineers at my hosting company who stated: "it looks like there's something wrong with how K2 creates URLs. Please try K2 support forums for that."
Is there any known issue with the versions of software mentioned above concerning webmaster tools?
