Commit c576054539790bdeb35285f62863d74b48c0782d removed the chunklist collection stored in ChunkProviderServer, however it has been partially restored in some places by 7e1ac0a77129b169704c1e222ff2deb3ab6cd2d2. As not all references to this were restored, this has caused the chunklist and chunks collections to become out of sync, resulting in a memory leak.
