This has been observed only on backport repo https://github.com/openjdk/shenandoah-jdk21u
Very rarely (and more frequently on aarch64 than x86), we encounter the following abnormal termination of jtreg test gc/shenandoah/TestAllocIntArrays.java#aggressive:

This typically happens less than 1 out of a hundred executions. Note that this test is configured with -XX:+ShenandoahOOMDuringEvacALot.
This test runs in 1G heap size. Typical freeset log_status() reports over 960M available to the mutator.
