I make load test with WebLoad. I created agenda with WebFT and changes it. Now the test-program loads main page of a web-application, then loads varuous application's pages in cycle (submitting forms - with POST-method (a push-button click)). Test-program works OK if I run it as functional test under WebFT.
If I run test-program as load test under WebLoad Console at least with 1 client, the program works normally only during 1 - 3 rounds. Then the program hangs up because of memory problem (tomcat continuous to work without exceptions, but it makes nothing).
Memory problem: memory usage by httpload128.exe process (Windows Task Manager) increases from 21mB to 63mB, difference (CommittedBytes - AvailableBytes) increases to 80-100 mB.
If I retard test-program's execution e.g. with allowing log-file-messages or with increasing sleep time (Sleep-function), the program works a little more time, but also ends in described memory problem.
Maybe, somebody knows solution of this problem ?
Check the Webload documentation. There are minimum hardware requirements.
I have the similar problem with WebLOAD. I have 2 servers for load generator and one regular computer for webLOAD console. It really looks like there are memory leak in the tool. However, it only happened on part of the application of the product I tested on. Eventually, httpload128.exe process will eat up all the avaliable memory and the tool will crash. Sometimes, I see 2 httpload128.exe processes running at the same time.
If I remember correctly, it was not really related to minimum hardware requirement. The problem began after the software update.
I wander if anyone other than me and compqs encounters similar problems.
Which version of webload are you using?
In webload 5.0 and earlier versions, we can define the number of httpload128.exe per number of virtual users.
e.g. one httpload128.exe for 20 virtual users.
In case, if you have more system resources and still httpload process crashes then you can use this option.
