Regenerate Thumbnails always cause 500 internal server error after update to 1.6.1.0

[bu_marius]

Hello,

 

Has anybody this problem?

 

I just finished to update my 1.6.0.14 to 1.6.1.0 and in the back office when I try to see all the products I have 500 internal server error!

 

Sometimes I have also:

 

Fatal error: Out of memory (allocated 79429632) (tried to allocate 6400 bytes) in /classes/ImageManager.php on line 484

 

and all the Thumbnails are white.

 

I have tried to remove all the product_mini pictures in the /img/tmp directory but nothing to do.

 

Sometimes I have some Thumbnails but not for all the products.

 

Regards

Marius
