Stephen Mallette commented on TINKERPOP-2504: --------------------------------------------- Thanks for looking into this. We do have a number of these kinds of tests that rely on timers that will fail with low resource environments. Perhaps some could be re-written or otherwise improved, but many will be difficult to reconstruct i think. I'm not sure I want to do that for this issue as this one is focused on tests travis routinely fails on. unless you think these failures are indicative of a real bug, I'd say that we should open a different issue related to "Low resource test failures" to try to fix up these tests which "might" fail in travis. what do you think? > Intermittently failing server/driver integration tests > ------------------------------------------------------ > > Key: TINKERPOP-2504 > URL: https://issues.apache.org/jira/browse/TINKERPOP-2504 > Project: TinkerPop > Issue Type: Improvement > Components: driver, server > Affects Versions: 3.4.9 > Reporter: Stephen Mallette > Priority: Minor > > I've noticed this test failing intermittently on Travis and more consistently > on the {{master}} branch with Docker. It fails with a > {{ConcurrentModificationException}} (haven't been able to easily get the > entire stack trace thanks to the docker issue and i've not caught it > happening in the last few days on Travis). Adding this line of code seems to > have made the test pass more consistently: > https://github.com/apache/tinkerpop/commit/4b099b3c84a350aae953cdf517aa11c7017eb2ae > which would indicate something perhaps fishy with how hosts are being marked > dead and iterated.
