I'm not sure what's causing it, possibly a funny character in the password?
Actually what happens is that the asp.net cache (System.Web.Caching.CacheSingle) is somehow being corrupted. It has a private member "_publicTotal". This integer somehow get a negative value. This is no problem for ordinary get and set operations, but when umbraco in umbraco.cms.businesslogic.cache.Cache.ClearCacheByKeySearch() tries to CreateEnumerator() it blows up!
It's correct that an app-pool recycle will solve the problem.

Hi Naorem
Have you checked if there is enough space on the disk of both the webserver and the database server?

Hi Matt,
Did resolve your problem? I have the same problem on a site running 4.9
Afraid not, it was left with my client's support desk provide more information and troubleshoot.
If I find out more I'll let you know.
Apparently they just just recycled the app pool to fix it.

These guys had the same problem: http://our.umbraco.org/forum/getting-started/installing-umbraco/32906-Umbraco-in-load-balanced-environments-in-conjunction-with-DFS
Does anyone have an idea how this can happen?
is working on a reply...
