Hi,
Based on your reply that I think I got the reason.
The instance I met this issue is a slave, so there are some updates by REPLICATION from from master. unfortunately, these updates are blocked by the running select(which will use tmp table in disk and cost a lot of time), than these updates lock the other reading operation.
Since the "show full processlist" can not show the REPLICATION, so I misunderstand there are not updates.
thanks for your help!
