OK, I may have found a possible solution - the max_connections MySQL setting [1]. For now I set it to 1000 and it seems to work.
Could be that the default of 151 was eaten up by all the OpenStack services, but it still seems more like a connection leak in my opinion. If nothing else, it's a documentation bug, because I followed all the Icehouse installation docs and there was no mention of setting this for MySQL.
