Unable to re-index due to locked file

Auto-index, as well as manual index, will not work due to a file (_10.cfs) being locked (not able to delete.) It seems as though it's always the same file. When I look at the processes that have it locked, it's start-bamboo.exe itself that has it 'in-use'. It seems to have a total of seven file handles open at the time.

I can re-index if I stop bamboo, delete the file, then restart bamboo. Following is the relevant portion of my log file:
