Stack overflow in session.js

[Dan Morphis]

I'm not sure of the cause. I started seeing a bunch of these show up in my
logs. I'm not sure which request in the log actually caused the SO.

session.js like 700 is the callback below:

  if (sessionContext.virtualParameters.length === 0 &&
sessionContext.declarations.length === 0 && !(_declarations != null ?
_declarations.length : void 0) && (sessionContext.doneProvisions ||
sessionContext.provisions.length === 0)) {
    return callback();
  }


cwmp.js line 422 is the return session.rpcRequest line:
nextRpc = function(sessionContext) {
  return session.rpcRequest(sessionContext, null, function(err, fault,
id, acsRequest) {
    var alias, channel, flags, j, l, len, len1, len2, len3, m, n, o,
p, ref, ref1, ref2, ref3, ref4, t, task, taskId;
