Note: this is a Type=Bus error vmState=0x00020019 so it might be a machine issue.

To rebuild the failed tests in =https://ci.adoptopenjdk.net/job/Grinder, use the following links:

[bragaigor]

I have just used the link above to rerun the test and it passed here:
https://ci.adoptopenjdk.net/job/Grinder/2280/
It might be an intermittent failure, so I'll try to run for a few more iterations

[pshipton]

@bragaigor pls connect with @JasonFengJ9 and try to recreate it internally on the same machine where it originally occurred.

[JasonFengJ9]

@pshipton the internal build info has been passed to @bragaigor and @dmitripivkine .

[dmitripivkine]

@pshipton the internal build info has been passed to @bragaigor and @dmitripivkine .

unfortunately test results were not stored (this is not implemented by Test team yet)
So I expect the grinder would not store results too. Seems we need to try to reproduce manually on machine

One more occurrence at Test_openjdk14_j9_extended.functional_s390x_linux_Nightly/37.

This kind of crash can occur in case if application is attempting to use more shared memory then Linux limit specify. Problem is understood, fixing in progress.

[dmitripivkine]

Double mapping feature has been redesigned and free from this defect.
