FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - process out of memory

问题原因：appium取android日志，内存没有释放，一直在增涨。

解决办法：本地appium安装目录找到logcat.js文件，例如路径在C:\Program Files (x86)\Appium\node_modules\appium\node_modules\appium-adb\lib\logcat.js

打开文件，注释掉如下2行内容：

Logcat.prototype.onOutput = function (data, prefix) {
  if (!this.logcatStarted) {
    this.logcatStarted = true;
    if (!this.calledBack) {
      this.calledBack = true;
      this.onLogcatStart();
    }
  }
  data = data.trim();
  data = data.replace(/\r\n/g, "\n");
  var logs = data.split("\n");
  _.each(logs, function (log) {
    log = log.trim();
    if (log) {
      var logObj = {
        timestamp: Date.now()
      , level: 'ALL'
      , message: log
      };
      //this.logs.push(logObj);
      //this.logsSinceLastRequest.push(logObj);
      this.emit('log', logObj);
      var isTrace = /W\/Trace/.test(data);
      if (this.debug && (!isTrace || this.debugTrace)) {
        logger.debug('[LOGCAT' + prefix + '] ' + log);
      }
    }
  }.bind(this));
};
