There’s a very big (4GB) file on my server called ‘common.diag’. What is this file about? May I delete it?

I’ve read this post before. Thx anyway.

However, my situation is slightly different:

My file is not located in domino\trace directory, but it’s in the root directory

My file is not growing … It’s just sitting there with the same file size of 4GB.

I really don’t know, if I can delete it, or not.
