SA tests fail due to memory alloc issues

      The following three SA tests failed due to memory alloc issues
      in the JDK14 CI:


      The test config included these options which might be relevant:

      -XX:+UseParallelGC -XX:+UseParallelOldGC -XX:+UseNUMA

      Here are snippets from one of the hs_err_pid files:

      # There is insufficient memory for the Java Runtime Environment to continue.
      # Native memory allocation (malloc) failed to allocate 2097152 bytes for AllocateHeap
      # Possible reasons:
      # The system is out of physical RAM or swap space
      # The process is running with CompressedOops enabled, and the Java Heap may be blocking the growth of the native heap
      # Possible solutions:
      # Reduce memory load on the system
      # Increase physical memory or swap space
      # Check if swap backing store is full
      # Decrease Java heap size (-Xmx/-Xms)
      # Decrease number of Java threads
      # Decrease Java thread stack sizes (-Xss)
      # Set larger code cache with -XX:ReservedCodeCacheSize=
      # JVM is running with Unscaled Compressed Oops mode in which the Java heap is
      # placed in the first 4GB address space. The Java Heap base address is the
      # maximum limit for the native heap growth. Please use -XX:HeapBaseMinAddress
      # to set the Java Heap base and to place the Java Heap above 4GB virtual address.
