+Encountered oom on lxchosts. Turned out that octavia wsgi was using huge amounts of ram. 
+First we disabled the apache on all octavia to prevent more oom kills.
+After that Erik limited their allowed memory usage, and we turned them back on.
+Found out that we can see what script is ran by apache in the vhost config. Turned out to be some CGI script.
+To profile the memory usage I stopped apache and ran a memory profiler directly against the cgi script, I had to stop the LB from using TLS but apart from that it worked smoothly.
+We now have a flamegraph of the memory usage, and it looks like it is something to do with ovs.
