I had executed a load test scheduled for 8 hours with 7 business flows, for maximum of 100 concurrent users. The test though stopped after 7 hrs 35 minutes. After checking the application logs i found that there was no problem in there also the application was working fine after 7 hrs 35 mins of test completion.
The only error that i could see was 1 one of the 5 load generator machines had failed.
The following error could be seen in the output file:
Error -29992 : Client (-server_type=0)(-server_name=dl7233new)(-server_port=54345)(-user_extra_data=NAMEdl7233new) is not responding. [MsgId: MERR-29992]
Any specific reason why a load generator machine has failed? The machine was not shut down during the execution.
Also am I right in concluding that the probable reason for the test not to complete 8 hours is the failure of the load generator.
1) What load generator are you using?
2) Did you check the network? (i.e. did you lose comms with the agent?)
3) Have you reproduced the error?
4) Have you tried a test for 6 hours? 7 hours? 7:30? 7:36?
5) Have you tried the same test with only the 4 load generation machines that didn't fail?
6) That's a large test - did you run out of ram/hard drive space on the agent?
If you have only executed the test once and only received the error once, you do not have enough information to conclude anything. I'd say that it's a reasonable theory that the test did not complete due to the failure of the load generator, but you still need to prove that.
I can think of maybe 2 dozen reasons why a load generation machine might fail, but with the information you have given it is impossible to speculate.
This sounds like a LoadRunner load generator? You might want to check that the Load Generator host didn't run out of memory.
I've had a similar problem in the past where a Load Generator host machine simply ran out of memory causing the Controller/Load Generator to stop communicating and this is likely to be quite a while into your test.
