Error 227, one more time

[patrick_dubois]

I have an error 227 when searching in one of my vaults

Tried :

- stop Autodesk, SQl and Web services, deleted VaultServer\Indexes, relaunched services

- forced a full re-index of file properties

- enabled Content indexing Services

no error in windows Events

I find in vlog-aaaammdd.txt
