I have a script where I set it to run for 16 hours with 100 VUs, and after couple of hours into the test, most VUs are in their 3000 iterations, and 4,5 VUs have the red cross and stopped at 200th iteration, and the error message is like this:
VU 37 : FAILED : Line 548 : WWW Post_To: WWW_ERROR_00147 -- No data available in response from host testmachine51:8080, error: (0) The operation completed successfully.
MAX_CONNECTION_RETRIES is set to 100.
other options are default.
This problem happens once in a while, and line numbers are different from time to time, and it's really annoying.
What other options can I adjust to make it constantly retry on errors.
The errors were caused by network fluctuations, I know this because I have another machine set up with browser level web UI automation targeting the same deployment and has proper logging. And UI automation experienced a couple timeouts as well, but it's configured to retry 100 times, and was able to recover from the error and resulted in 99.5% of passing rate which is acceptable.
And on the other hand, QALoad had around 85% of passing rate which rendered the test useless....
