Tried that and also tried deleting the dovecot.index.cache and running 
again, same result.

The cache file is around 1 G
1070635444 Dec  1 12:06 dovecot.index.cache

It could be hitting the 1 GB limit on cache file size, but I assume this 
would show in the logs? If this is the reason, is there any way around it?
