I'm having some issues on various D7 sites with some cache tables growing stupidly large (e.g
cache_menu) which then makes
drush cc all very slow (more than 1 minute).
Do you think that there is any problem if I setup a nightly linux cronjob which will be truncating
cache_* tables apart from
cache_form? And after that I plan on executing a
drush cc all for safety.
p.s I do not plan on investigating and trying to fix the root cause that makes those tables grow large.
