并发情况下，会出现大量连接错误

[GREATDOGHEAD]

项目down下来，想测试一下性能，20个线程并发请求get接口，共请求8000次，出现了大概50%的错误，错误日志如下：

Thread Name:Thread Group 1-20 Sample Start:2022-10-24 16:18:10 CST Load time:0 Connect Time:0 Latency:0 Size in bytes:2080 Sent bytes:0 Headers size in bytes:0 Body size in bytes:2080 Sample Count:1 Error Count:1 Data type ("text"|"bin"|""):text Response code:Non HTTP response code: org.apache.http.NoHttpResponseException Response message:Non HTTP response message: 127.0.0.1:8083 failed to respond

大佬有空可以帮忙看看这个问题吗。
