One exchange DB copy queue length extremly high

I have exchange 2016 DAG with many DBs. I see one passive DB has an extremely high copy queue length. Others are ok. What could cause it?

Hi @alangao-5587

Is the affected passive DB on the same node as other DBs?

Like Andy said, the most common cause of the issue is network.

Network or disk issues typically.

If it continues, consider reseeding that database:
