What this does is provides the capability to allocate memory for a process from the memory module which contains the processor that caused the page fault.

这样做的目的是，在内存模块中为处理器上产生缺页的进程提供内存分配的功能。

If the problem does not happen on a single-processor system with JIT off, that might be an indication that JIT is not at fault.

如果这个问题不会在禁用jit的单处理器上发生，那么这就可能说明JIT不是问题的根源。
