使用restore命令导入mongodb数据库时遇到一些问题。我使用普通的mongodump命令转储数据库，然后尝试使用mongorestore在本地服务器中恢复它。问题是当集合中的文档数量很少时导入成功，但是当文档数量较大时，服务器崩溃。日志的堆栈跟踪在下面给出

有谁能告诉我背后的原因。那么远程服务器是64位的ubuntu，而我的本地服务器是32位的ubuntu。这可能是崩溃的原因。我的意思是我刚刚使用了简单的mongodump和mongorestore，那么为什么它会崩溃服务器。
另外我不明白; mongodb不稳定或总是面临分段故障问题。任何见解??
答案 0 :(得分：0)
收藏品有多大？两台服务器都有相同数量的物理内存吗？ Mongo会尽可能多地将工作集存储到内存中，但是如果你正在恢复的服务器的RAM大大减少，则可能导致问题。
