I have a cron job that sends emails to a list of subscribers, one at a time in a foreach loop, with a PDF attachment. I got this message from the cron script:\[code\]Fatal error: Allowed memory size of 94371840 bytes exhausted (tried to allocate 78643193 bytes)\[/code\]What do I need to do to prevent this error?Also, I'm pretty sure that it didn't finish sending to all the subscribers, so how should I keep track of this so it knows where to pick up again if it didn't send to everyone?Updater: Here's a code sample: (I'm using the Zend Framework by the way)\[code\]public function send(Default_Model_MyEmail $myEmail){ if (null != ($id = $myEmail->attachmentId)) { $file = new Default_Model_File(); $file->find($id); $filepath = APPLICATION_UPLOADS_DIR . '/' . $file->getActualFilename(); $attachment = new Zend_Mime_Part(file_get_contents($filepath)); $attachment->type = $file->getMimeType(); $attachment->disposition = Zend_Mime:
ISPOSITION_ATTACHMENT; $attachment->encoding = Zend_Mime::ENCODING_BASE64; $attachment->filename = $file->getDisplayFilename(); } $transport = new Zend_Mail_Transport_Smtp('localhost'); $mail = new Zend_Mail('utf-8'); $mail->setFrom('from@address', 'From Name'); $mail->setReplyTo('replyto@address'); $mail->setSubject($myEmail->subject); if (isset($attachment)) { $mail->addAttachment($attachment); } $subscribers = $this->getSubscribers(); foreach ($subscribers as $subscriber) { $mail->addTo($subscriber->email); $bodyText = $myEmail->body . "\r\n\r\nIf for any reason you would like to be removed from this mailing list, " . "please visit \r\nhttp://myapp.com/myemail/unsubscribe/email/" . $subscriber->email; $mail->setBodyText($bodyText); $mail->send($transport); $mail->clearRecipients(); }}\[/code\]Update: I am reusing the \[code\]$transport\[/code\] variable. I was under the impression this was the correct way to send to multiple subscribers, but maybe this is the cause? What do you think?Update: I've added a bunch of log statements that print memory usage statements, but I don't really know what to do now. The memory usage increases with every email. With a subscriber list of 200, it gets to 160 then runs out of memory. What should I do?
