      I ran into this error while running 2.0.4 and upgraded to 2.2.0 and the problem went away. After two/three days after upgrading the problem came back but disappeared after a mongod restart. Could this be related to a memory leak?

      I'll try to fix a simple test case but essentially I have five monitoring scripts sending log data to a PHP script via a REST interface.

      Some more system info:

      > db.stats();
      {
      "db" : "kpsommar3",
      "collections" : 6,
      "objects" : 72223,
      "avgObjSize" : 211.56794926823866,
      "dataSize" : 15280072,

      "fileSize" : 469762048,
      "nsSizeMB" : 16,
      "ok" : 1
      }
      >

      % ulimit -v -H

      I'd love to help debugging this one to get rid of it once and for all.
