 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.

+
+QA with Webglobe team, who are developing another control panel. Was short. Happy that Rutger was there, they asked some question that I wouldn't be able to answer easily. Which means there is a gap in my knowledge. I added a note about this in my kast.
+
+We did an interview with Ali. Ali has prior OpenStack experience and seems like a chill guy. We'll have a technical interview at the office on Tuesday. Looking forward to it!
+
+On Wednesday we were supposed to have an interview with Isabel who couldn't make it. Haven't heard yet if she will meet with us another time.
+
+Fixed nexthop/gateway in Puppet neutron. Learnt that updating Puppet dependencies in the normal way is nearly impossible. Simply slapped the commit hash in the lock file instead.
+
+Encountered OOM situation due to Octavia. Learned a little bit about memory profiling. Not yet found the actual cause sadly.
