I currently have a Magento site version 1.9.1.0 and have the "Front controller reached 100 router match iteration" reports. It's bringing down the site several times a day.
I have followed the steps in this post Magento "Front controller reached 100 router match iterations" error
and when the site went down last I believe the controller that seems to reappearing is the '/admin' path as shown in
2015-09-19T16:55:02+00:00 DEBUG (7): ----Matching routers-------------- ----------------
2015-09-19T16:55:02+00:00 DEBUG (7): Total 7: admin, standard, install, wordpress_addon, cms, wordpress, default
2015-09-19T16:55:02+00:00 DEBUG (7): - Iteration 1
2015-09-19T16:55:02+00:00 DEBUG (7): Request: [path_info=/admin] [module=][action=][controller=][controller_module=][route=]
There is redis, varnish and memcache also running and the cache is saved to the database. When the site goes down I restart these services and it will fix the problem temporarily but obviously this isn't the solution. It also seems that the more I restart the services, the more it happens. This problem happened about a year ago and in order to rectify it, these were added and the problem seemed to be fixed but now has reappeared (badly).
I also found this post http://magentosupport.help/knowledgebase/solved-front-controller-reached-100-router-match-iterations/ which I have gone through each step and checked each one but still the problem hasn't been fixed.
I was going to try this patch https://github.com/convenient/magento-ce-ee-config-corruption-bug#update-good-news-a-patch-from-magento but my hosting company told me it wouldn't work because it doesn't apply to my version.
The site has multiple stores and lots of additional extensions, I would really appreciate it if anyone could give me any advice because I am desperately stuck.
Kind Regards,
