MemoryError when using imaplib fetch

Please help me, I am getting MemoryError when trying to fetch a specific email. This is the error message:

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

MemoryError

And here is my code:

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

I am using python 2.3.5

Thanks in advance!


A MemoryError usually indicates that your system ran out of free memory. Perhaps your Python script is keeping references to all messages it's seen and the total sum of them is too big to fit in memory?


http://bugs.python.org/issue1092502

The suggested fix there by a_lauer seems to have fixed my problem.
