| August 7 - we found out that PhOptimization algorithm starts leaking memory if it fails to find proper values. If running one setup, the test might go through. However, if multiple modules are tested in parallel and they all start leaking memory at the same time, the system will kill one testboard process (or two if necessary), causing the unlucky testboard(s) to get stuck (powered on, HV on, but no tests running) until they are reset. Current solution to this problem is to simply omit the PhOptimization if the fulltest procedure. We left gainPedestal, since it will use default Ph dac values. |
