Broken/missing handler views 2 Drupal 6 Recently I created a new Content type and Added a bunch of CCK fiekds in it. After that I migrated some contents to the system using node_save() function.

Everything was fine until I cleared the cache then 3 of my existing views broke and started to say "Views Broken/missing handler" in some of the fields and in filters. Though the fields do exist as the CCK fields in the proper content type.


See the attached image 
When I try to remove or modify the field then it says "An illegal choice has been detected. Please contact the site administrator." Also the field formats is not show. Refer to the below image. 
These fields though exist in the CCK as per the below image. 
To make the site working again I have to go to the Content type's Manage Fields page and click on save. Then it starts to show in proper way (Followed: https://drupal.org/node/624826). The problem is if I clear cache then again this happens. 
I had backed up the database before the migration and once I saw this then I DROPPED the total database and again imported the sqldump in the blank database but then again once I cleared the cache it again showed Broken/missing handler.


I am totally confused here. Searched Google but didn't got a proper solution. After dumping the old database still its happening. Is it that Views and CCK is storing something while I created the CCK? We are using Memcache in the system, but I suppose that has nothing to do with it.

Please help me on this.
I have found that MAX OPEN FILES can have an impact along with maximum size of object, my understanding is this is the case with or without memcache but I have not proved that yet. I created a tool with cURL to log broken views when they occur and use Munin to monitor everything as it happens: https://drupal.org/node/89710#comment-8351855
