Hi,

if you delete the template cache in the backend you will probably get a timeout in a large cluster environment.

This query lasts several minutes at one of our installations:

UPDATE ezdfsfile SET mtime=-ABS(mtime), expired=1 WHERE name REGEXP
'^var/cache/designbase_.*$'

bin/php/ezcache.php is also affected, clearing the template cache lasts ages.

Best wishes,
Georg.
