递归process.nextTick警告

作为我的应用程序的一部分,我有以下几行代码:

process.nextTick(function() {
  // pre-populate cache with all users
  console.log('scanning users table in order to pre-populate cache');
  tables.users.scan(function(err, users) {
    if (err) {
      console.error('unable to scan users database in order to pre-populate cache');
      return;
    }

    console.log('found %d users in database', users.length);
  });
});

在ubuntu中运行应用程序给了我

(node) warning: Recursive process.nextTick detected. This will break in the next version of node. Please use setImmediate for recursive deferral.

RangeError: Maximum call stack size exceeded

在OSX上运行工作正常,没有任何警告.

两者都运行相同的节点版本v0.10.24.

删除此代码块可解决此问题.我想知道这里发生了什么.

试图用--trace-deprecation旗帜显示运行节点

与运行--throw-deprecation提供了

任何帮助非常感谢.
