I really don't like the look of those malloc errors. It appears that it's
only asking for 4.89 MB of memory, which is not a lot really. Googling for
this error code gives examples of people with the problem, but they're
typically asking for more than a GB of memory (at which point the error is
Is there plenty of free space on the drive that's being used for the swap?
Do any other programs have memory troubles?
Is there a fairly large message in the IMAP folders that it's scanning
through? (perhaps something about 4.9 MB?) Python's imaplib tries to
receive the whole message in one chunk, meaning (I presume) that the memory
is requested in one chunk, but if that's a problem then it's a Python
problem and I would have thought that some other OX X 10.3 Python user would
have hit it. (The google results did have a few Perl hits, though).
Could you try this and see what happens?
>>> import imaplib
>>> i = imaplib.IMAP4("my.mail.server")
>>> i.login("username", "password")
