All of a sudden I started getting sporadic HTTP 503 errors on my WordPress blog, as well as this error:
Fatal Error xc_fcntl_lock errno:9 in Unknown on line 0
These appeared both on user pages and admin pages, but never consistently.
The problem was made to go away by disabling XCache in my .htaccess file.
Anyone know anything about this? I tried looking on the XCache site but it just returns 503 errors on all the pages :shock:
