我带有PYDEV的LICLIPSE在项目打开后开始冻结几秒钟。我已经检查了更新而没有成功。当冻结时，Liclipse消耗了约48％的CPU和300 000 kb的内存（消耗太多的内存可能是可以的）。
编辑：它在项目不运行时冻结，它只是在Eclipse中打开！
我已经尝试删除.metadata并从头开始导入项目，但是这个问题再次发生。
我怀疑当我打开一个特定的py文件时会发生这种冻结，那里有很长的字符串（我正在处理请求 - 帖子）。
这是来自.metadata的一块日志，但它可能不包含根据时间冻结的问题（最后记录的问题 - 15:56，最后冻结-15：58）：

在哪里可能是问题？
不幸的是，日志似乎没有太大帮助（所示条目应该无害）。
我认为您是对的，因为代码可能有一些模式，因此由于某种原因而导致它反复出现，因此，如果它是公开的，您是否可以指出我，以便我可以尝试将其打开以复制/解决错误？
否则，当发生这种情况时，替代方案可能会将某些剖面剂固定在蚀上，然后将输出传递给我（即https：//www.yourkit.com/，如果您将某些vmargs传递给Eclipse，则可以将其附加到运行程序上.ini -https：//www.yourkit.com/docs/80/help/agent.jsp）
另一个选项可能是获得Eclipse SDK，PYDEV源代码（http://pydev.org/developers.html），然后进行一次调试会话，然后按debugger暂停，以查看可能发生的事情...
