icinga periodically reports high MW exceptions, these in particular seems to affect jobrunners mostly, on de / fr / no / commons wikis, last 24h logstash: https://logstash.wikimedia.org/goto/56ac3eabbb84953b3d92e69b3ca56f60
browsing through phabricator for a similar error message it looks like we've seen this before, e.g. T67263
