python-2.7 - zerorpc 客户端在调用不存在服务器超时超过 1,000 次后将卡住

Question

我使用 zerorpc 来构建我的 rpc 程序，但我发现了一个有趣的现象，

代码

import zerorpc

c = zerorpc.Client(timeout=0.1)
c.connect("tcp://192.168.33.12:4242")

count = 0
while True:
    print(count)
    try:
        print c.hello("RPC", async=False)
    except zerorpc.exceptions.TimeoutExpired as e:
        print(e)
    count+=1

** 上面的服务器不可达，会一直打印超时信息，但是超过1000次就卡住了gevent.queue.Channel.put()，我试了很多次，1000的数字是固定的，不知道为什么？**

输出

992
timeout after 1s, when calling remote method hello
993
timeout after 1s, when calling remote method hello
994
timeout after 1s, when calling remote method hello
995
timeout after 1s, when calling remote method hello
996
timeout after 1s, when calling remote method hello
997
timeout after 1s, when calling remote method hello
998
timeout after 1s, when calling remote method hello
999
timeout after 1s, when calling remote method hello
1000
timeout after 1s, when calling remote method hello
1001
