It caused by stap test case. I minimized the test cases to

TEST_SUITES = "ping date ssh systemd stap kernelmodule gcc "

which could reproduce the error.

And it PASSes testimage that remove stap test from default TEST_SUITES:

TEST_SUITES_remove = 'stap'

But I can't reproduce the OOM failure to run stap tests manually.
