Yes, the duplicate file entry is always reported immediately before the 
crash, just as Ralf reported too. You can see it in this example 
pastebin I took from one of our users:

Correct. All index, control files, amd mail storage are located on NFS 
and there are multiple load balanced servers accessing the NFS data. 
We're currently running with:

mmap_disable = yes
dotlock_use_excl = yes
fsync_disable = no
mail_nfs_storage = yes
mail_nfs_index = yes
