Can someone help me for some reason today my logs show three seperate errors these are 439, 482 and 473. They say that something in a database maybe corrupt this is said to be in the catroot2 folder, can anyone tell me what is stored there and how to fix it please? 
edit: it said insufficient resources and that the file was âpartially detachedâ

The suggested articles have give me some way of fixing this issue but I shall see if it happens again and get back to you, although I am worried as to what (if any) data has been corrupted ???
