I think the only thing we can do in this case is to just go through the market actor deals, and look for related deal proposal

This can also be made much less likely to happen by setting larger confidence numbers when getting DealID, but that increases deal-to-sealed-sector latency even more

My lotus-miner got idle after this error. The number of sectors in "PreCommit1" status has increased overnight, but the lotus-miner process is simply idle.

@Stebalien I put this in the "markets" backlog but it is really a StorageFSM ticket -- you may want to look at it.
