Glynn, do these failures occur for you if you just run the individual tests, or just do a mvn clean install in a lower level module? We have had some problems with macOS where they do not recycle file descriptors fast enough, so if all tests are run together then there are delays waiting for available FDs... and many of our tests are a little time sensitive (eg wait 250ms and then test result). Can you try increasing the ulimit on your machine/account for file descriptors to at least 10000.

Haven't tried that. I'm only trying top-level builds now. > > We have had some problems with macOS where they do not recycle file descriptors > fast enough, so if all tests are run together then there are delays waiting for > available FDs... and many of our tests are a little time sensitive (eg wait > 250ms and then test result). > > Can you try increasing the ulimit on your machine/account for file descriptors > to at least 10000. Perfect. BUILD SUCCESSFUL. Thanks! I'll close off the other bugs. (In fact this *seems* to help with at least one other problem we were struggling with where our documentation build was left hanging trying to stop the Apache fop renderer.) I needed to set ulimit -n 10000. Glyn, glad that helped.... although it is still a bit of a worry that macOs appears to need that (and that we have quiet a few timing sensitive tests). cheers (In reply to comment #4) > Glyn, > > glad that helped.... although it is still a bit of a worry that macOs appears > to need that (and that we have quiet a few timing sensitive tests). > > cheers I wouldn't worry too much. Sometimes test environments can be a bit peculiar compared to production environments. I captured the ulimit stuff in some machine setup instructions [1] on the Virgo wiki. Maybe it would be worth doing that in the Jetty wiki too? Just a thought. Glyn [1] http://wiki.eclipse.org/Virgo/Committers#Machine_Setup |
