Memory Limit Reached When Switching Currency

Question

I have a strange bug, wonder if anyone can help.

Scenario

have an empty cart
switch to euros
Loads fine
Add a product to cart
Loads fine
Switch back to pounds
Site hangs and then crashes
Site cant be reloaded until all cookies are deleted

Error Message

[Thu Jun 12 12:11:56.419992 2014] [:error] [pid 2652] [client xxx] PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 7 bytes) in /var/www/lib/Zend/Db/Statement/Pdo.php on line 290

As you can see my memory limit is 1024m which is WAY more than enough, so it must be something else :/ just not sure what.

Thoughts?

Do you have any code customizations with regards to currencies or cart? Or is this a plain Magento install? — mpaepper, Jun 12 '14 at 12:10
I have a custom module on the cart update observer, turned that off and still get this. We're also running about 40 other modules. I've added a list above... — user9123, Jun 12 '14 at 12:27
step one by one through all 42 modules seems a little hard core, my site will stop functioning after a few disables anyway. There has to be a better method for working this out? — user9123, Jun 12 '14 at 12:38
Nope, that is the cost of using so many extensions. You can copy the site and test on another instance of it, that's just the way it goes, badly behaved extensions cause all these types of problems. We would say to put you on a very high spec server with high memory to test, but you probably have budget constraints, so back to testing the plugins one by one. Currency may be a red herring, the checkout is the most resource intensive process so it could be related to the item in the cart. — , Jul 23 '14 at 10:48
Has this been solved? I have the same issue on my site. Extensions in common:- AW_All Ebizmarts_SagePayReporting Ebizmarts_SagePaySuite Fooman_GoogleAnalyticsPlus Phoenix_Moneybookers Webshopapps_Matrixrate — Paul Semple, Jul 23 '14 at 10:22

Try

htaccess

Or

ini_set("memory_limit", “512M"); in

index.php

'msp' is a reference to a custom module...one I do not have. – user9123 Jun 12 '14 at 13:08
Probably best to reference the original post here: http://www.magentocommerce.com/boards/v/viewthread/667076/#t466834 – Douglas Radburn Jun 12 '14 at 13:08
Its always better to share the code then links, because links may break or may not work. – TBI Infotech Jun 12 '14 at 13:09
Either way in this case, the code just isn't relevant. But thanks for trying. – user9123 Jun 12 '14 at 13:25
Not good, lets just all debug together again – TBI Infotech Jun 12 '14 at 13:26
Answer updated please try this – TBI Infotech Jun 12 '14 at 13:30
I appreciate the help here, but just guessing at answers or stripping answers from the MC forums isn't massively helpful :/ my memory limit is being set to 512M you can see that from the error message. – user9123 Jun 12 '14 at 13:48
As you are using modules, what best I can do is share my thoughts, I have hence updated – TBI Infotech Jun 12 '14 at 13:49
User9123 - I've definitely seen this before on a site I've worked on, but I can't find the solution. Currently back-tracking through lots of commits :) – Douglas Radburn Jun 12 '14 at 13:53
TBI, thank you for trying.
Douglas, Thanks :)

extension=pdo.so extension=pdo_mysql.so

?

Is this issue fixed? – TBI Infotech Jun 16 '14 at 12:26
it not good idea to increase memory limit...........disable one by one module and Check Which extension is create issue.Then check where the issue – Amit Bera Jul 23 '14 at 10:34

This usually happens when you use subpar templates, or whoever built the theme was not following the Way of Magento. Often everything seems to work just fine at first, but at some point things starting to fall apart at random moments, usually with memory limit errors (for example, I don't think the switch itself is culprit in your case).

Vinai Kopp wrote a great article about scalability you should check. Perhaps it helps you to find the real reason why you run out of memory:
