[Bro] Question on log rotation

I had a situation where log rotation and post-processing (summary 
emails) were not completing. New logs would get started and each 
previous hour's logs renamed, but not get compressed and moved, which 
means that many of the previous logs were still in /current (or are they 
really in <path-to-bro>/spool/manager?). In any case upon stopping bro 
via broctl it appears that only the most current log got processed and 
archived while all of the logs in between that never got processed seem 
to simply have gotten deleted. Are those logs simply lost or somewhere 
other than the dated archive folder and /current folder? If so, is this 
expected behavior, or is there normally something that would check to 
see if previous logs failed to rotate out?
