      There's a cheap, rude, crude, fix that I've used   
      for a number of units ... crontab a reboot at maybe   
      midnight. Clears all bullshit and errors from memory   
      and maybe only 60 seconds of downtime.   
      
      Linux/PI is good, but some kinds of errors and/or   
      memory leaks DO seem to accumulate despite best   
      efforts.   
      
      Crontab a root @reboot to get everything going again.
