Can i run owncloud on a raspberry pi b+ with 128mb memory split?

i´m trying to use my RPi as a OC server and a steam stream box which requires 128mb memory split. when setting it to 128 the streaming works, but i can´t complete a simple .jpg upload to OC when at 128mb. is there any way to make OC work at 128 or is there a way of changing the memory split without rebooting?

You could disable thumbnail generation. For php the limit was 128 or 256 MB if you want to use thumbnail generation (+ database + webserver +...). ownCloud is not running that fast on a RPi, then even sharing with other resources, ...

Worked like a charm! Thanks
