[Debian-pan-maintainers] Bug#1026864: dmrgpp: flaky autopkgtest on amd64: times out

[Paul Gevers]

Source: dmrgpp
Version: 6.02-3
Severity: serious
User: debian-ci at lists.debian.org
Usertags: flaky timeout

Dear maintainer(s),

I looked at the results of the autopkgtest of your package. I noticed 
that it regularly fails on amd64 because it times out after 2 hours and 
47 minutes. Apparently this only happens on our most powerful worker: 
ci-worker13, but not all runs there time out. I'm wondering if this 
might be a race condition that the test only experiences with lots of 
CPUs (64) or lots of memory (256GB) (and depends on the load of the system).

Because the unstable-to-testing migration software now blocks on
regressions in testing, flaky tests, i.e. tests that flip between
passing and failing without changes to the list of installed packages,
are causing people unrelated to your package to spend time on these
tests.

Don't hesitate to reach out if you need help and some more information
from our infrastructure.

Paul
