1. The worker has been waiting for tasks, and has not received the tasks distributed by miner

2. lotus-miner sectors list。
   Four tasks are stuck in precommitwait. Is the status of this task abnormal

Could you please try the latest master? If the issue is still there, whats your lotus version? and whats your hardware spec?

could you please also provide lotus-miner sealing jobs and lotus-miner sealing workers?

[jennijuju]

Please also provide lotus-miner info all for investigation, thanks!

We'll definitely need the Lotus version to look into this
