    <div>More than once, probably about six
      times.<br>
      <br>
      One can rebuild the user file and restart the node. All is then
      well for a while. I believe I have seen it work for more than one
      week, but within another week or two it will revert to an empty
      user file. It MAY be related to spawned jobs which write to the
      user file thus corrupting the user file, but not every time and,
      in any case, I can't see any spawn jobs that might do a write. I
      am reluctant to put in file spin locks but it may become
      necessary. It MIGHT be memory usage, but there is no objective
      evidence for a lack thereof. <br>
      <br>
      Mike seems to have the only instance of "standard" (i.e. non-mojo)
      DXSpider that can (at least for a time) support 1000+ users on
      quite a lowly single processor GCloud instance - and seemingly
      with room for many more. As you know Ian, us lesser mortals start
      to see serious CPU usage above about 4-500 users (depending on
      processor). And worse, it appears that the mojo branch runs like a
      snail on mogodon on an identical instance in the same data centre.
      Which is the exact opposite of anyone else's experience. <br>
      <br>
      Mike is unwilling to run his node on dedicated hardware for
      perfectly reasonable reasons. But otherwise, I am stumped.<br>
