Not surprising due to delayed allocation, if cache writeout pressure isn't high then this will happen. The "workaround" would be for transmission to periodically flush the filesystem but that'll just cause awful IO spiking latency and defeat the purpose of delayed allocation.
If you'd rather not lose that much data, then perhaps you need a more aggressive dirty_writeback
