Memory leak using symfony2 & swiftmailer

I use the symfony2 command as a cron job to send bulk email to site members.

Actual code:

$output->writeln('Before: '.(memory_get_usage() / 1024 / 1024));

$mailer->send($m);

$output->writeln('After: '.(memory_get_usage() / 1024 / 1024));

My results:

Before: 182.38 MB
After: 183.73 MB

Each time I send an email, the swiftmailer consumes an additional 1 MB of memory. It just doesn't seem right, but the memory grows every time a new message is sent. Am I something wrong here?

In my case, sending ~ 1,500 letters, the memory grew to ~ 100 MB (only due to the registrar), now> 0.2 MB.

I know this a bit later, but maybe it can be useful to someone who gets into the same problem. :-)
