【问题描述】：
我的带有 PyDev 的 LiClipse 在项目打开几秒钟后开始冻结。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 300 000 kb 的内存（消耗这么多内存可能还可以）。
编辑：当项目未运行时它会冻结，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，但这个问题又出现了。
我怀疑当我打开一个包含很长字符串的特定 py 文件时会发生这种冻结（我正在处理请求 - 帖子）。
这是来自 .metadata 的一段日志，但它可能不包含按时间冻结的问题（上次记录的问题 - 15:56，上次冻结 - 15:58）：
