IB TWS late day quote freeze

[SoesWasBetter]

Never had this problem for years until recently.

Inside the last minute of the day, (3:59) my stock quotes stop updating.

I assume its volume related and I have a good load on the cpu but no more than I did when it worked perfectly.

Anyone else see this with TWS?

Today around 3:50, my TWS sort of froze up as well.
Everything was updating fine, but two market orders I sent in returned errors, that they weren't yet received by the exchange.
I restarted TWS and found that both market orders had indeed gone thru, and that for some reason TWS hadn't received the "Transaction Completed" message.
A little alarming, to say the least.

That's a different kind of error.

The one I'm seeing in within the last minute of the main session only, and clears itself a few seconds after the 4pm close.
