### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Version 0.14.12 ### What's Wrong? Start 4 jmeter processes, each jmeter process has 200 threads, and an error sendFragment timeout is reported after a period of stress testing. After closing all jmeter processes and starting a jmeter process and there is only one thread, the sendFragment timeout error is still reported. It is suspected that the client somewhere is not released:  Detailed: ``` 2021-09-02 18:31:42,112 WARN (doris-mysql-nio-pool-361|642) [Coordinator.sendFragment():571] exec plan fragment failed, errmsg=Waited 5000 milliseconds (plus 89075 nanoseconds delay) for io.grpc.stub.ClientCalls$GrpcFuture@1e14cbd9[status=PENDING, info=[GrpcFuture{clientCall=ClientCallImpl{method=MethodDescriptor{fullMethodName=doris.PBackendService/exec_plan_fragment, type=UNARY, idempotent=false, safe=false, sampledToLocalTracing=true, requestMarshaller=io.grpc.protobuf.lite.ProtoLiteUtils$MessageMarshaller@68db04c6, responseMarshaller=io.grpc.protobuf.lite.ProtoLiteUtils$MessageMarshaller@53f9d004, schemaDescriptor=org.apache.doris.proto.PBackendServiceGrpc$PBackendServiceMethodDescriptorSupplier@683faf26}}}]], code: TIMEOUT, fragmentId=F00, backend=192.168.32.10:29060 2021-09-02 18:31:42,112 WARN (doris-mysql-nio-pool-361|642) [StmtExecutor.execute():406] execute Exception. {} org.apache.doris.common.UserException: errCode = 2, detailMessage = query timeout. backend id: 10004 at org.apache.doris.qe.Coordinator.sendFragment(Coordinator.java:577) ~[palo-fe.jar:3.4.0] at org.apache.doris.qe.Coordinator.exec(Coordinator.java:469) ~[palo-fe.jar:3.4.0] at org.apache.doris.qe.StmtExecutor.handleQueryStmt(StmtExecutor.java:863) ~[palo-fe.jar:3.4.0] at org.apache.doris.qe.StmtExecutor.execute(StmtExecutor.java:343) ~[palo-fe.jar:3.4.0] at org.apache.doris.qe.StmtExecutor.execute(StmtExecutor.java:288) ~[palo-fe.jar:3.4.0] at org.apache.doris.qe.ConnectProcessor.handleQuery(ConnectProcessor.java:206) ~[palo-fe.jar:3.4.0] at org.apache.doris.qe.ConnectProcessor.dispatch(ConnectProcessor.java:344) ~[palo-fe.jar:3.4.0] at org.apache.doris.qe.ConnectProcessor.processOnce(ConnectProcessor.java:545) ~[palo-fe.jar:3.4.0] at org.apache.doris.mysql.nio.ReadListener.lambda$handleEvent$0(ReadListener.java:50) ~[palo-fe.jar:3.4.0] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) [?:1.8.0_292] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) [?:1.8.0_292] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_292] ``` ### What You Expected? win ### How to Reproduce? _No response_ ### Anything Else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
