Test fails due to truncated hs_err file

Test: runtime/ErrorHandling/MachCodeFramesInErrorFile.java

[2021-10-20T16:13:20.284271Z] Gathering output for process 10908
----------System.err:(14/836)----------
java.lang.RuntimeException: 0 < 2
at jdk.test.lib.Asserts.fail(Asserts.java:594)
at MachCodeFramesInErrorFile.run(MachCodeFramesInErrorFile.java:161)
at MachCodeFramesInErrorFile.main(MachCodeFramesInErrorFile.java:106)

But the hs_err log for process 10908 is truncated:

#

x14=

And that is the end of the file.

No indication as to why the hs_err file should be truncated.

Bug filed for CI tracking purposes but I don't see anything that can be done here.
