Question

我们使用zeo服务器和三个zeo客户端。 Zope版本是2.13.19

它运行正常，但我想了解为什么以下某些连接已连接且未连接。

最终，只有三个连接显示收到的握手，这三个客户端占据了这一点。

SIGTERM暗示允许的最大RAM的阈值被取代，就像它可能在虚拟服务器上发生一样，在这种情况下，您将要升级您的主机计划，以获得更多的RAM

如果您确实重新启动了操作系统，或者您自己以另一种方式使用SIGTERM的原因，这也可能发生，原因可能各不相同，可以是缓存验证，如第64行的ZEO-5.1.1-py2.7.egg/ZEO/cache.py源代码：

# When the client is connected to the server, it receives
# invalidations every time an object is modified.  When the client is
# disconnected then reconnects, it must perform cache verification to make
# sure its cached data is synchronized with the storage's current state.

所以一般来说，没有什么可悲的，客户端会尝试连接和断开连接，直到建立有效的连接。

然而，在更改生产中的任何内容之前，始终在前台的暂存或开发环境中启动实例始终是一个好主意。
