I've actually seen what I think he is describing.  It seems to happen when I
reply to a message using my reader.  It happens rarely and randomly, so it's
difficult to reproduce.  I've noticed it in Windows (I think Psi-Jack is
running Synchronet in Linux?).

The other day I made a small JavaScript script that opens a sub-board with a
MessageBase object, lets a user post a message while that MessageBase object is
open, then closes the MessageBase object.  I was trying to reproduce the issue
in Linux where if a JS script has a MessageBase open and lets the user post a
message in that sub-board, the MessageBase wasn't getting updated as far as the
number of messages.  I ran that small script on my Linux test setup, and while
that script didn't reproduce that issue, I did see it crash Synchronet multiple
times after I had saved my message.  I tried it in my Windows Synchronet setup,
and I didn't see it causing a crash there.  This is the code (substitute the
value of the subCode variable with a valid sub-board code on your BBS):

load("sbbsdefs.js");

subCode = "loc_general";
var msgbase = new MsgBase(subCode);
if (msgbase.open())
{
  console.print("\1n\r\n# of messages (before posting): " + msgbase.total_msgs
                + "\r\n\1p");
  var msgHdr = msgbase.get_msg_header(true, msgbase.total_msgs-1, true);
  if (msgHdr != null)
  {
    bbs.post_msg(subCode, WM_NONE, msgHdr);
    console.print("\1n\r\n# of messages (after posting): " + msgbase.total_msgs
                  + "\r\n\1p");
  }
  msgbase.close();
}
