问题:运行场景后,提示“Abnormal termination, caused by mdrv process termination”,服务端没有挂,仍可正常访问,且在运行场景时,没有自动重启。找下了,网上的答案如下:

f the LR articles. The Loadrunner vusers are run by a process called 'mdrv.exe'. Whenever this process encounters errors due to various reasons it may terminate. Some of the possible reasons are as follows
- The Host machine ( Load generator) is running too many Vusers as a result of which it system resources are being maximized. ( i.e. Consistent over 90% CPU and Memory utilization). The mdrv process does not get enough resources to process the request as a result it fails
- If you have Custom C coding, there is a possibility of allocated memory not being freed or memory violation errors which can lead to 'mdrv process termination'.
- Replay the script with think time.
- Turn off extended log when running the script in the controller.
- Do not use the controller itself as the loadgenerator.
i.e. have a remote LoadGenerator. - Introduce iteration pacing, if running more than one iteration each vuser.
- Open the file C:\WinNT\wlrun7.ini in a text editor, modify the entry from: AgentMaxThreadsPerDriver
=50 to AgentMaxThreadsPerDriver =20 or 10 - Run Agent as process instead of service Launch command prompt and navigate to C:\Program Files\Mercury\Loadrunner\Launch_service\bin and run the command magentserive -remove. This will remove the agent. Now run the command magentproc -install This will install the agent as a process.
- Run vusers as process instead of threads.Please go to Runtime Settings > Miscellaneous > Multithreading > RunVuser as a process.
另外,注意下负载机的连接数是否过高,往往测试TPS较高的应用或是Client本身导致连接来不及释放会引起mmdrv进程Crash。当然加入Thinktime或者Pacing Time是种办法,一般最小可设置0.1~1s,但毕竟指标不治本,需要更多的用户来测试系统最大处理能力。
