RangeError: Invalid array length

[claude2]

I started seeing the error below after March 17. My code was not changed, I did not upgrade any libraries, or the node version. The code is a ticker monitoring program which uses reqMktData on about 15 contracts. The example reqMktData works fine.

/home/claude2/ib/node_modules/ib/lib/incoming.js:1229
      this._dataQueue = this._dataQueue.concat(dataQueueSnapshot);
                                        ^

March 17 is the key... that's when several monitored contracts expired. I'll try to give reproduction code but it's something like monitoring expired futures contracts:

ib.contract.future('ES', '20170317', 'USD', 'GLOBEX', 50),
