Comment (by John.H.Haller@…):
Since the semaphore guarding the data structure is only held while
manipulating a map structure and never held over a function call other
than the map, this looks like a data corruption problem, not a lock
problem, perhaps a use after free bug.
In my case, this mostly happens after the front-end suffers a very long
response time on a disk write:
