Fatal error: memory size

Hi all,

i ahve been trying to create a backup and restore functionality for a custom modue, and altough it seems quite simple, after i add the:

$this->add_step(new backup_moduçe_activity_structure_step('module_structure', 'module.xml'));

in the define_my_settings() function, after that i get th:

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 523800 bytes) in /home/muffles/public_html/moodle/backup/util/helper/backup_general_helper.class.php on line 190

error. I have tried to remove everything from the stepslib file, in the define_structure function, and it still returns that error. I have no idea what is wrong.

 

I have increased the memory_limit, cleared caches, etc, nothing worked...This is actualy not doing anything atm so...

PS: Using moodle 2.0

 

Thank you

Hi

You have mentioned memory_limit. Have you also increased post_max_size (and upload_max_filesize; although as it is on your server this should not be as necessary)?

Perhaps you might be better off posting this in the Developer's forum - you think?

Possibly; although I did also think that it might help other people who have a similar problem when they backup any course e.g. http://moodle.org/mod/forum/discuss.php?d=187816&parent=819406

I did not suggest to Mahtab to increase his post_max_size (didn't think of it then) if he bumps his post or googles (if he has not found a solution) it might help (which is why I also added the bit about upload_max_filesize).

Might be something to update in the FAQ (if increasing these php values does help):

I am having this same issue. I cannot restore anything. 

 

Any advice?

Have you tried increasing memory limit by going to Site Administration - Server - Performance. By default is 128mb and you can increase up to 1024mb.

Thank you for responding! 

Yes, I did increase the limit at that location to 1024 - I'm still getting the error. cURL and bitrate are set to defaults of 120 and 56 respectively. 

I cleared cache just in case it helped with anything (I'll pull at straws!). 

I also had tried the information on the Back Up FAQ page - about using the .htaccess file and the php.ini file. Changing the php.ini file also did not seem to do anything; and for some reason if I have an .htaccess file at all, it bombs the site (no access at all), so I was not able to do anything there. 

Is there something else I can try? 

 

Oh. I am on 2.1.1 - and have not made any changes since the last time I ran back-up/restore and import, which all worked fine at that time.

Probably try turn debugging on and see what error message you get. From my experience, some of the third party modules or blocks may cause the backup/restore process to stall.

I turned debugging on before I searched/posted for help smile 

 

Fatal error: memory size - various files depending if I'm trying to install or import. 

 

Now, when I go to create a new course from back-up, it gets to the last screen and goes blank (except for the error messages - it says it doesn't want to add the Paypal info, then also gives the "Fatal error: memory size" - EXCEPT it does add that new course.)

 

(for the record, it has never added the paypal info automatically - no matter what/when; so now I see it was a minor error and perhaps it was supposed to be adding all along - but that does not seem to be what is breaking anything)

 

I have done no updates, adding mods, etc since this past October when I last tried to restoring from back-ups. NOTHING has changed on my end, except the size of the back-ups.
