did you try increasing memory limit in wp?
woo recommends min of 128M allocated to wordpress:

how to increase memory for wordpress
https://docs.woocommerce.com/document/increasing-the-wordpress-memory-limit/
just throwing out ideas here
did your site stop working because of this or did the slider only stop working?
I am considering updating to 3.9.1 and do not want to break my site.
thx for your time
