请帮助我,我在尝试获取特定电子邮件时遇到MemoryError。这是错误消息:

python(23838,0x1888c00) malloc: *** vm_allocate(size=3309568) failed (error code=3)
python(23838,0x1888c00) malloc: *** error: can't allocate region

MemoryError

这是我的代码:

resp, content = _mailConnection.fetch(num, '(RFC822 FLAGS)')

我正在使用python 2.3.5

提前致谢!

MemoryError通常表示系统的可用内存不足。也许你的Python脚本会保留对它所看到的所有消息的引用,并且它们的总和太大而不适合内存?
