My PHP memory limit is set to 64M, and I am testing registration of multiple participants.

There are no problems when I don't enter email addresses for subsequent participants, but when I do, I run out of memory (backtrace included below).

1. Is the recommended memory limit still 64M? Perhaps that ought to be updated on the documentation.
2. The 1.9M of memory being allocated when it fails seems to be for the email message template for the subsequent participants. Can the memory for the first template be freed prior to allocating this?
3. Can I instrument my code to tell me how much memory processes are using? If such a failure occurred "in the wild" I would have disgruntled constituents, but perhaps no idea that this is a problem.

Thanks for a brilliant 3.1!

I increased my PHP memory limit to 100Mb (if only I could do that between my ears ...).

All is good.

My concern is that unless this sort of error is logged, and that log is sighted, I might be blissfully unaware of this sort of fault. Note that CiviCRM does log its errors into files called <JOOMLA-ROOT>/media/civicrm/templates_c/en_US/ConfigAndLog/CiviCRM.*.log (not sure what the Drupal equivalent is), so you can monitor error logs.

Thanks, Piotr.

I know from previous experience how tricky memory leaks can be to track down. Thanks for your effort,

Ken
