我的LiClipse与PyDev在项目打开后几秒开始冻结。我检查了更新但没有成功。当它被冻结时，LiClipse消耗大约48％的CPU和30万kb的内存（消耗这么多内存可能没问题）。
编辑：当项目没有运行时会冻结，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文件时会发生这种冻结，其中有一个非常长的字符串（我正处理请求 - 帖子）。
这是来自.metadata的一段日志，但它不包含根据时间冻结的问题（上次登录的问题 - 15:56，最后冻结 - 15:58）：

哪里可能是问题？
答案 0 :(得分：1)
Unfortunately the log doesn't seem to help much (the entries shown should be harmless).
I think you're right in that there's probably some pattern in the code which is making it recurse for some reason, so, if it's public, can you point me to it so that I can try to open it to reproduce/fix the error?
Otherwise, an alternative could be attaching some profiler to Eclipse when that happens and pass me the output from it (i.e.: https://www.yourkit.com/ can attach to a running program if you pass some vmargs to eclipse.ini -- https://www.yourkit.com/docs/80/help/agent.jsp)
Another option could be getting the Eclipse SDK, the PyDev source code (http://pydev.org/developers.html) and then do a debug session and press the debugger pause to see what may be happening...
