节点在Garbace集合期间崩溃,但没有任何其他高级模式(可能与https://github.com/nodejs/node/issues/3715相关)。
幸运的是,我没有任何代码可以复制,因为我无法隔离问题。
这是使用segfault-handler模块捕获的崩溃堆栈跟踪:

还有一次这个堆栈:

有人能给我一些关于如何找到问题的暗示吗?感谢
如果您愿意,还可以回答我创建的节点问题: https://github.com/nodejs/node/issues/11606
其他信息: 节点框架:express,Sails.js
我使用find node_modules -name '*.node'
建立的原生模块是:
node_modules/bcrypt/build/Release/bcrypt_lib.node
node_modules/bcrypt/build/Release/obj.target/bcrypt_lib.node
node_modules/segfault-handler/build/Release/segfault-handler.node
node_modules/segfault-handler/build/Release/obj.target/segfault-handler.node
答案 0 :(得分:0)
这些问题似乎是由mongodb日志引起的,这些日志会占用磁盘空间。实际上很难看到,因为我们会定期清理它,所以在我检查的那一刻并不重要。
