Hi @tuohai666
When I insert 100 threads, I now see two phenomena. One is that during the insertion process, null pointer exceptions occur once or twice.
At this point it seems to be in a blocking state, with the CPU close to 0%. Table data is not growing either.After a while, it inserts normally.
The other is to keep throwing null Pointers.At this point, Instead of using 1 thread insert, the null pointer will also be reported.
But if the Proxy is restarted, 1 thread is fine.

@xzpoul The exception was most likely an MySQL server error exception.
I compared the codes between 4.1.0 with 5.0.0, and found that the former may burst Unknown exception while the latter will throw the Exception same as MySQL server.
To find out the cause of this exception, I suggest updating the Proxy to 5.0.0 version.

@xzpoul This exception shows that there are not enough connections available. You can simply change maxPoolSize to 100 or more to solve this problem. But please make sure that your MySQL server instance can afford this concurrency.
