java.lang.Thread.run(Thread.java:679) This eventually leads to a bunch of slaves no longer appearing to be connected to our master jenkins, restarting the master does not affect this, and we need to restart the slaves individually. Notably this does not affect all our slaves. (But the ones that are affected, are always the same ones!)
