No, almost everything is working fine. I can view and add contacts, and I even managed to do an export of hundreds of contacts today.
I can create mailings fine, but another function I'm having trouble with is sending them out, in that it's sending them out at a snail's pace. Again, it seems to be the same out of memory error. Here's what the logs say:

Have already contacted host about this to see if it's a problem on their side, but I wonder also if there's some kind of memory leak going on with civi.
