ProblemList java/nio/channels/DatagramChannel/ManySourcesAndTargets.java on macosx-aarch64 - Resolved

Description

The following two tests failed in the JDK17 CI:

java/nio/channels/DatagramChannel/ManySourcesAndTargets.java
java/nio/channels/DatagramChannel/InterruptibleOrNot.java

I'm filing a single bug for these two failures because the test
executions overlapped in this sighting.

DatagramChannel/ManySourcesAndTargets.java failed due to a
timeout and here's a snippet from the log file:

Another sighting on JDK 17 CI: https://mach5.us.oracle.com/mdash/jobs/mach5-one-jdk-17-0-4+1-54-tier2-20220206-1535-28854748/results?search=status%3Afailed+AND+-state%3Ainvalid macosx-aarch64: jpg-mac-arm-38.oraclecorp.com
07-02-2022
There are currently 21 failure sightings for: java/nio/channels/DatagramChannel/ManySourcesAndTargets.java in the JDK17 and JDK18 CIs. The only sighting of: java/nio/channels/DatagramChannel/InterruptibleOrNot.java is the original 2021.03.29. 20 of the ManySourcesAndTargets.java sightings are on macosx-aarch64. In order to reduce the noise in the JDK18 CI, I'm looking at ProblemListing ManySourcesAndTargets.java.
05-01-2022
[~msheppar] I don't think we should change test to use a Selector and non-blocking I/O. That is just working around an underlying issue. It's okay to exclude this test on macos-aarch64 while the issue is being investigated. The DatagramSocket.setSoTimeout method should set the timeout for DatagramSocket.receive. The socket adaptor does support it. Nothing to do with DatagramChannel.receive of course.
22-09-2021
It's impossible to tell if there firewall, configuration, or other tests running concurrently that are leading to the scenario where the IPv6 datagrams are being discarded. In the case of ManySourcesAndTargets, I think we should at least change it to run in /othervm mode to improve the changes that the trace messages will be in the .jtr file. Also change testReceive to replace reader.send(..) with sender(..) to avoid confusing readers.
16-08-2021
[~msheppar] Well spotted, it should be sender.send(..). The sender is bound to the wildcard address as it needs to send to all addresses so I don't think it's really an issue but we should change it anyway. The test logging is in the .jtr and maybe changing the IIPv6 enabled run to /othervm might help there.

Slack notes on these failures with [~alanb]: Alan Bateman:spiral_calendar_pad: 8 hours ago DatagramChannel/InterruptibleOrNot.java also failed on jpg-mac-x64-023 in this run. If this machine was super slow at this time then it would explain both failures. Daniel Daugherty 21 minutes ago DatagramChannel/InterruptibleOrNot.java ran for 8 seconds and failed. DatagramChannel/ManySourcesAndTargets.java ran for 8+ minutes and timed out... Alan Bateman:spiral_calendar_pad: 17 minutes ago InterruptibleOrNot will fail in this wait if the system hangs for 2 seconds, we could increase the wait time but it would of course increase the duration of the test Daniel Daugherty 16 minutes ago DatagramChannel/InterruptibleOrNot.java started at Mon Mar 29 07\:00\:58 GMT 2021 and ended at Mon Mar 29 07\:09\:12 GMT 2021. DatagramChannel/ManySourcesAndTargets.java started at Mon Mar 29 07\:00\:57 GMT 2021 and ended at Mon Mar 29 07\:01\:04 GMT 2021. So there's about a 6 second overlap between the two tests execution windows. Daniel Daugherty 14 minutes ago According to "top": 2021/03/29 07:09:17 Load Avg: 18.33, 15.30, 9.02 CPU usage: 71.62% user, 15.67% sys, 12.70% idle so the machine was fairly loaded when DatagramChannel/InterruptibleOrNot.java executed. Daniel Daugherty 12 minutes ago For both tests, this is the only failure sighting in Mach5. Daniel Daugherty 10 minutes ago InterruptibleOrNot will fail in this wait if the system hangs for 2 seconds, we could increase the wait time but it would of course increase the duration of the test 2 seconds? Wow that's a tight tolerance. Alan Bateman:spiral_calendar_pad: 3 minutes ago Okay although I’m 99% sure this is infrastructure. We can increase the tolerant on one of the tests Daniel Daugherty < 1 minute ago The test task ran with a concurrency of 6. Perhaps DatagramChannel/ManySourcesAndTargets.java needs a timeout slightly longer than the default two minutes. With a timeout of 180 and a a default timeoutFactor of 4, it will have 12 minutes to execute when it happens to run with other tests in parallel.
