Sometimes Node will run for days without this error, but other times I will get it back to back in a short period of time.  I have seen comments to the effect that it is there to catch programming errors or unexpected conditions and that it one case it was someone's misuse of an API, but I can not find where anyone has elaborated on what the issue actually was or what types of errors cause it. Any help with tracking this down and determining if it is an error in my code or in another component would be greatly appreciated."},"comment":{"url":"https://api.github.com/repos/libuv/libuv/issues/comments/146423589","html_url":"https://github.com/libuv/libuv/issues/401#issuecomment-146423589","issue_url":"https://api.github.com/repos/libuv/libuv/issues/401","id":146423589,"user":{"login":"cynron","id":4964823,"avatar_url":"https://avatars.githubusercontent.com/u/4964823?v=3","gravatar_id":"","url":"https://api.github.com/users/cynron","html_url":"https://github.com/cynron","followers_url":"https://api.github.com/users/cynron/followers","following_url":"https://api.github.com/users/cynron/following{/other_user}","gists_url":"https://api.github.com/users/cynron/gists{/gist_id}","starred_url":"https://api.github.com/users/cynron/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/cynron/subscriptions","organizations_url":"https://api.github.com/users/cynron/orgs","repos_url":"https://api.github.com/users/cynron/repos","events_url":"https://api.github.com/users/cynron/events{/privacy}","received_events_url":"https://api.github.com/users/cynron/received_events","type":"User","site_admin":false},"created_at":"2015-10-08T05:24:29Z","updated_at":"2015-10-08T05:24:29Z","body":"@fmsouza \r\n\r\nbacktrace when crashing?\r\n\r\n    $ gdb /path/to/node /path/to/core/file\r\n\r\nand then type command `bt` in gdb.\r\n"}}
