Hello everyone, Our last nightly build on RHEL linux x64 failed because the test dxtbx/tests/tst_dxtbx.py , which normally takes roughly 3 seconds to run on the build machine, got stuck for over 5 minutes. All the other tests (cctbx/scitbx/libtbx/iotbx/rstbx and remaining dxtbx) completed successfully. Tests were run via libtbx.run_tests_parallel with nproc=4. As far as I can tell there is no debug output. The libtbx testing suite does not support timeouts like some timeout decorators on python unittest? As far as I can tell tst_dxtbx.py at the moment runs 5 separate tests, so for future debugging it may make sense to split these up. -Markus -- This e-mail and any attachments may contain confidential, copyright and or privileged material, and are for the use of the intended addressee only.
