I didn't have it in mail_always_cache_fields, but I had looked at 
doveadm mailbox cache decision and seen the fields mentioned in the log 
as being in cache as temp.

I just tried adding hdr.MESSAGE-ID to mail_always_cache_fields and tried 
to fetch but with the same result. Good idea though.
doveadm cache decision only tells me what dovecot will try to keep in 
cache, is there some why of inspecting the cache itself to know what is 
stored there? I've had to raise vsz_limit because of out of memory 
situations, so maybe the cache is corrupt? Nothing about it in logs though.
