Linux
一段時間後返回結果時出現遠端 jmeter-server 錯誤
我有一個問題，我正在使用我的電腦上的 jmeter，它驅動安裝在 RHEL5.8 上的 jmeter-server
我的java版本是：
[jmeter@sem-osb logs]$ cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.8 (Tikanga) [jmeter@sem-osb logs]$ java -version java version "1.7.0_51" Java(TM) SE Runtime Environment (build 1.7.0_51-b13) Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)我的電腦執行 ArchLinux。在兩者上我都使用相同版本的 Jmeter，即：jmeter.JMeter: Version 2.11 r1554548
所以我嘗試執行一個簡單的測試，對soap webservice有3個請求，並嘗試模擬2個永遠執行這些請求的客戶端（我想載入伺服器）。
一段時間後，我在 jmeter-server.log 上收到以下錯誤：

如果您需要更多詳細資訊，請詢問。

解決方案是使用此參數，似乎當您打開太多連接時，用於舊連接的埠在 TIME_WAIT 狀態下停留時間過長，因此這有助於：
