在做一个文本分析的项目，需要调用哈工大语言云的API，URL中需分析的参数是一段文本。哈工大语言云的API调用有频率和大小限制，GET方法大小不超过10K，同一个IP不能超过200次/秒，所以我设置了每读26次文本sleep 0.1秒，把调用结果分段写入另一个文本，但每次都在写入文本达到166kb的时候报以下异常
java.io.IOException: Server returned HTTP response code: 493 for URL: http://api.ltp-cloud.com/analysis/?api_key=somethingpersonal&text=%E7%8E%B0%E5%9C%A8%E8%BF%99%E6%97%B6%E4%BB%A3CPU%E6%80%A7%E8%83%BD%E8%BF%87%E5%89%A9%E9%AD%85%E8%93%9D%E9%82%A3%E7%A7%8D%E7%83%82CPU%E9%83%BD%E8%83%BD%E7%8E%A92k+2015+%E7%8E%B0%E5%9C%A8%E6%A0%B9%E6%9C%AC%E4%B8%8D%E7%9C%8Bcpu+%E7%9C%8B%E5%B1%8F%E5%B9%95%EF%BC%8C%E6%91%84%E5%83%8F%E5%A4%B4%EF%BC%8C%E7%9C%8B%E8%BD%AF%E4%BB%B6%E6%89%93%E5%BC%80%E9%80%9F%E5%BA%A6%EF%BC%8C%E5%B0%8F%E7%B1%B3%E7%94%A8%E5%9B%BD%E4%BA%A7%E9%97%AE%E9%A2%98%E5%B1%8F%E5%B9%95%EF%BC%8C%E4%B8%80%E7%9C%8B%E5%B0%B1...%2F%2F%E3%80%905%E5%AF%B8%E5%B1%8F+%E9%AA%81%E9%BE%99808+Type-C+%E5%B0%8F%E7%B1%B34c%E6%AD%A3%E5%BC%8F%E5%8F%91%E5%B8%83%E3%80%91+http%3A%2F%2Ft.cn%2FRyii7e9&format=conll&pattern=all

at LtpAPI.SimpleAPI.main(SimpleAPI.java:86)求助各位大神，我在网上找到的有关错误493的只有以下：
493 Undecipherable
The request was received by a UAS that contained an encrypted MIME body for which the recipient does not possess or will not provide an appropriate decryption key. This response MAY have a single body containing an appropriate public key that should be used to encrypt MIME bodies sent to this UA.
实在不明白了，前面可以正常调用，为什么每次走到同一个地方就报这个错误咧？...
