nGrinder 3.2 Agent Error
Locked
 
|
Hi,
I deployed nGrinder 3.2 controller and Agent in my Windows 7 PC. When I execute any tests they are terminating with SCRIPT_ERROR message. I executed the same in one of the Unix virtual machine and I faced the problem again. When I run the 3.1.2 Agent against 3.2 controller, the script was working fine. When I compare the Agent 3.1.2 and Agent 3.2, I saw additional jars included for Groovy support. I attached the Agent logs below. 2013-05-30 17:11:07,417 INFO agent controller: agent is started. waiting for ag ent controller signal 2013-05-30 17:11:07,422 INFO net.grinder.AgentDaemon: The Grinder

How much memory is free in agent before running the test? In your log message -Xms-26m shows that the available memory is calculated as a negative value. Previously nGrinder used "actual free memory" which includes the memory occupied for some buffer but be able to released in case of lack of memory. However we found out that this can cause OS crash much.. so nGrinder 3.2 are using "free memory" to calculate the java memory. You case shows that the free memory is less than 300MB(this part is reserved for OS safety) as well. Could you run task manger and see how much free memory is?

Thanks for the explanation Junoyoon..
I was running controller and agent in same machine. On top of that I opened Browser (Multiple tabs) and Mail applications.. My machine RAM Size 4GB RAM (Core 2 Duo 2.48 GHz). I closed all the other apps and I executed only controller and agent in my machine. This time I am able to run the tests with 3.2 Agent.. When I run more applications in background, due to lack of memory the agent is failing to execute the tests. Hereafter I will ensure my machine has enough memory to run the tests. Thanks again. |
