configure transientStorePoolEnable = true

This log means the waiting time of the send requests waiting in request queue is beyond max waiting time (200ms).
You can try set transientStorePoolEnable=true to decrease the pressure of Page Cache

Or, you can increase the waiting time limit in send request queue.

sh mqadmin updateBrokerConfig -b {brokerIP:port} -k waitTimeMillsInSendQueue -v 3000

@xunianchong If you are using the master-slave deployment mode, it is a good choice to turn on transientStorePoolEnable, but if it is in raft mode, this parameter has no effect. You need to first determine whether it is data synchronization (network) or the problem of slow pagecache writing.
Besides, the waitTimeMillsInSendQueue can be a little bigger.
