Re: [wildfly-dev] Call For Help (Testsuite)

Well the problem is that you really need more than one core to catch timing & memory visibility issues.

I'm asking for everyone's help in doing what we can to make them stable. If you submit a PR, and you see what looks like an intermittent failure, can you do some investigation and report your findings even if it is not your area? It would be awesome if you can report what you find to the mailing list, and rope in help. >>>>>> >>>>>> Nearly all of these seem to only occur when virtualization is involved, so if need be we can work out a plan to create either a special run to capture diagnostic info, or I can give access to a dedicated slave. >>>>>> >>>>>> If anyone has any further ideas on how to tackle these issues I am all ears. >>>>>> >>>>>> -- >>>>>> Jason T.
