During cross-space compaction, sometimes due to the selection strategy of the
selector, the system may execute compaction tasks that require a large amount
of memory. The memory demand of a single compaction task may be larger than the
total memory size allocated to the compaction module by the system. In this
case, these compaction tasks will be stuck at the memory allocation step,
waiting indefinitely. Subsequent compaction tasks cannot be executed either,
making the compaction module appear as if it has "stopped".
