今天我运行我的脚本进行文件系统索引以刷新RAID文件索引,并在4小时后崩溃并出现以下错误:
[md5:] 241613/241627 97.5%
[md5:] 241614/241627 97.5%
[md5:] 241625/241627 98.1%
Creating missing list... (79570 files missing)

服务器配备16GB RAM和24GB SSD交换。我非常怀疑我的脚本超过36GB的内存。至少它不应该
脚本创建存储为具有文件元数据的对象数组的文件索引(修改日期,权限等,没有大数据)
这是完整的脚本代码:http: //pastebin.com/mjaD76c3
我已经在过去使用这个脚本遇到了奇怪的节点问题,这迫使我如此。将索引拆分成多个文件,因为当处理像String这样的大文件时,节点会出现故障。有没有办法用庞大的数据集改进nodejs内存管理?
