[New-bugs-announce] [issue6311] virtual memory error with archivemail

[helgekraak]

New submission from helgekraak <helge at kraak.info>:

Hi,

I'm neither a Python nor a Unix specialist, so please understand that I
can't give a very professional bug report.

My issue seems to be related to issues 1092502 and 1389051. When I run
archivemail with Python 2.6.2 after a couple of minutes the virtual
memory in the activity monitor suddenly goes up to more than 2 GB and
then the python process quits as it seems to have reached a limit of the
virtual memory (the virtual memory available is about 10 GB). Most of
the time the virtual memory is stable around 40 MB and only sporadically
the memory suddenly increases to values between 100 MB and 2 GB but goes
back to 40 MB again until the one time that it goes so high that the
python process quits. The error happens much faster when I use a non
secured imap connection compared to a secured connection.

I get this error message:

command: archivemail --date='23 April 2030' --include-flagged
--output-dir=/temp  --copy  imaps://*****:*****@*****/inbox
