XF 1.5 Fatal Error: Allowed memory...

I see this error in the logs today:
ErrorException: Fatal Error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 12960 bytes) -library/XenForo/Image/Gd.php:78

Stack Trace:
#0 [internal function]: XenForo_Application::handleFatalError()
#1 {main}

Request State:
array(3) {
["url"] => string(69) "http://bluesguitarunleashed.com/forum/index.php?account/avatar-upload"
["_GET"] => array(1) {
["account/avatar-upload"] => string(0) ""
["_POST"] => array(8) {
["use_gravatar"] => string(1) "0"
["avatar_date"] => string(1) "0"
["avatar_crop_x"] => string(1) "0"
["avatar_crop_y"] => string(1) "0"
["_xfToken"] => string(8) "********"
["_xfNoRedirect"] => string(1) "1"
["_xfResponseType"] => string(9) "json-text"
["_xfUploader"] => string(1) "1"

Based on what I am reading here on the forum this is likely a PHP error where it's running out of memory. But what I cannot tell is if it's a PHP configuration error, or I've got something set too large (the avatar upload, for example.)

Can anyone direct me on how to handle this? Thanks.

This looks like it's down to a low memory_limit in PHP - it seems to be currently set to 64MB. As well as checking php.ini this may well be overridden elsewhere.

You could either raise the memory_limit in PHP or reduced the max allowed size for avatar uploads in XF.
