I have set up Jenkins slave Windows service so that it is restarted by system on failure. It works OK if slave fails for whatever reasons. Unfortunately recently master keeps failing due to out of memory problems and after master reboot some Windows slave do not reconnect. Service has to be restarted in order to connect slave again.

Note that before exception slave itself reconnected many times to master, but after exception it did not recover until service was restarted.
