Post From: Chart stops drawing bars — only full restart fixes it (Rithmic + Denali)

In one of the logs we see 75 messages containing this:
2026-06-25 12:28:34.445 | Caught an unhandled exception in c_DTCMessageProcessor::ProcessDTCMessagesWithStandardHeader

Once this is encountered you have to restart but we do not know why it is happening. It would seem as though there is faulty data coming from Rithmic but we do not understand why that would be leading to an exception.

We do not remember ever seeing this before.

We will look over that function and try to determine what could be causing the problem.
