   I doubt the write lock maybe not the root cause of this issue. 
   
   When checking `isProducersExceeded`, it will load policy data from zk if topic policy not configured. Once the first thread call `isProducersExceeded`, the policy will be cached, and the following check won't be blocked. 
   
   So in my opinion, you'd better check the zk read latency or there are something wrong in `ZooKeeperDataCache`. You can also the stack about ZooKeeperDataCache.
