[mxnet-label-bot]

Hey, this is the MXNet Label Bot.
Thank you for submitting the issue! I will try and suggest some labels so that the appropriate MXNet community members can help resolve it.
Here are my recommended labels: Test, CI

[vdantu]

@mxnet-label-bot add [test]
@apeforest

[roywei]

fixed in latest run, we can close this now: http://jenkins.mxnet-ci.amazon-ml.com/blue/organizations/jenkins/NightlyTestsForBinaries/detail/master/320/pipeline

[roywei]

actually, we can't close it yet, this test was fixed but went back to failing after #15059. Similar OOM issue in #14980

[roywei]

Currently, both CPU and GPU tests have been disabled due to the same memory issue. Had a discussion with @access2rohit and @apeforest, we can try a few things:

1. change to P3 instances here https://github.com/apache/incubator-mxnet/blob/master/tests/nightly/JenkinsfileForBinaries#L82
2. further increase shared memory to 50G
3. stop running large tensor test parallelly with other tests.

We are having problems testing the above solutions on CI machines that have multiple jobs running in parallel.

[roywei]

failed with 200G shared memory on P3.2x and failed, we need another approach for testing large tensor.
