[Plugin: Memcached Object Cache] Cache broken

Hi,
I have a serious problem with memcache for a couple of months.

I add some rewrite rules filter for a blog. It works fine but after some time, when the url is recalled, it returns a 404 not found.

I have to flush manually the cache to fix the bug every time.

Rewrite rules:

// <category>/archives/<year>/<month>
  add_rewrite_rule('(.+?)/archives/([0-9]{4,})/([0-9]{2,})/page/([0-9]+)/?$', 'index.php?category_name=$matches[1]&year=$matches[2]&monthnum=$matches[3]&paged=$matches[4]', 'top');
  add_rewrite_rule('(.+?)/archives/([0-9]{4,})/([0-9]{2,})/?$', 'index.php?category_name=$matches[1]&year=$matches[2]&monthnum=$matches[3]', 'top');

  // <category>/archives/<year>
  add_rewrite_rule('(.+?)/archives/([0-9]{4,})/page/([0-9]+)/?$', 'index.php?category_name=$matches[1]&year=$matches[2]&paged=$matches[3]', 'top');
  add_rewrite_rule('(.+?)/archives/([0-9]{4,})/?$', 'index.php?category_name=$matches[1]&year=$matches[2]', 'top');

  // <category>/archives
  add_rewrite_rule('(.+?)/archives/page/([0-9]+)/?$', 'index.php?category_name=$matches[1]&paged=$matches[2]', 'top');
  add_rewrite_rule('(.+?)/archives/?$', 'index.php?category_name=$matches[1]', 'top');

I am not able to reproduce the bug in the development environment.

Do you have some councils for me??
