我的问题是“为什么?” 和“我能做些什么来解决它?”。
在这种情况发生之前,它通常会持续一周左右。最后一次,处理tweepy挂起的 4 个线程中的 3 个(第四个正在等待来自挂起线程的信息)。奇怪的是,线程挂起之间有相当长的延迟:首先,线程调用api.followers_ids()挂起,然后大约 12 分钟后线程调用api.friends_ids()挂起,然后 1 小时 12 分钟后(!)线程调用api.search()挂起。在所有这些之间有许多 api 调用。
我在那里有一些代码可以在我发送QUIT信号时转储它的堆栈跟踪,并且我得到了类似以下内容的挂起线程。它们与(包括)第二个条目(tweepy/binder.py, line 185, in _call部分)完全相同。另外两个从tweepy/cursor.py, line 85 in next和到达那里tweepy/cursor.py, line 60, in next:

在线程挂起的时候有一些 tweepy 错误。这并不太罕见,尽管这个数字比正常情况略多。不过,第四个看起来很有趣……它发生在线程挂起之前。
[Errno 110] : Connection timed out在最后一次followers_ids()调用之前大约 7 分钟(中间有许多各种各样的 api 调用)[Errno 104] Connection reset by peer 大约 3 分钟后(再次,几次成功调用之间)[Errno 110] Connection timed out最后一次friends_ids()通话前约 1.5 分钟。这是在api.search()线程中,它在第一个线程挂起前大约 5 分钟就一直在等待 - 总共等待了大约 15 分钟。[Errno 104] Connection reset by peer在来自friends_ids()线程的最后一条消息之前大约 2 毫秒,并且在同一个线程中。刚刚收集的好友 id 页面显示一切正常,并且这些调用没有错误。[Errno 104] Connection reset by peer在search线程中,friends_ids线程挂起后大约 17 分钟和线程挂起前将近一个小时search。Failed to send request大约 1.5 分钟后无故出现TweepError。Failed to send request,还有3 个无理由的和 1[Errno 104] Connection reset by peer个。search并且有很多lookup_users调用search。| 归档时间: |
