我的带有 PyDev 的 LiClipse 在项目打开几秒钟后开始卡住。我检查了更新但没有成功。当它被卡住时，LiClipse 消耗大约 48% 的 CPU 和 300 000 kb 的内存(消耗这么多内存可能还可以)。
编辑:项目未运行时它会卡住，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，但这个问题又出现了。
我怀疑当我打开一个特定的 py 文件时会发生这种卡住，其中有一个很长的字符串(我正在处理请求 - 帖子)。
这是 .metadata 中的一段日志，但它可能不包含根据时间卡住的问题(最后记录问题 - 15:56，最后卡住 - 15:58):

问题出在哪里？
请您参考如下方法:
不幸的是，日志似乎没有太大帮助(显示的条目应该是无害的)。
我认为你是对的，因为代码中可能存在某种模式，由于某种原因使其递归，所以，如果它是公开的，你能指出它以便我可以尝试打开它来重现/修复错误？
否则，另一种方法是在发生这种情况时将一些分析器附加到 Eclipse 并将它的输出传递给我(即:如果将一些 vmargs 传递给 eclipse.ini，https://www.yourkit.com/ 可以附加到正在运行的程序 -- https://www.yourkit.com/docs/80/help/agent.jsp )
另一种选择可能是获取 Eclipse SDK、PyDev 源代码 ( http://pydev.org/developers.html )，然后执行调试 session 并按下调试器暂停键以查看可能发生的情况...
