For a larger codebase with framework code (angular) I am using this module. When several errors are thrown and several stracktraces are requested in a short succession memory usage spikes absolutely out of control.

Expected Behavior

Should require a little bit less memory per error.

Current Behavior

Memory spikes out of control.
This is how stacktraces are requested.

    StackTrace.fromError(err)
      .then((stackframes) => {
        return stackframes
          .splice(0, 20)
          .map((sf) => {
            return sf.toString();
          }).join('\n');
      });
