Exit relay named Libero (64.113.32.29) running on CentOS Linux, kernel
2.6.32-573.18.1.el6.x86_64 , Tor 0.2.7.6.
I started seeing crashes around the beginning of May, as so:

I increased the memory of the virtual server to 4 gigs around May 11, saw
it crash again on May 18.
I set up graphing on the memory after that, and it's not looking good. I'm
going to try to attach an.odf file (libreoffice draw) that shows what I'm
seeing.
It may have started shortly after an update.
If it helps you, I can get you into the vserver if you can get me an ssh
public key to install. You can email me at tor@xxxxxxx if you want for
that.
