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

Problem: My chart randomly stops drawing new bars even though the data feed is still connected and running, and order execution continues to work normally. The chart just freezes — no new bars are painted. What does NOT fix it: Reconnecting the data feed Reload and Recalculate The only fix: Fully close and restart Sierra Chart. This happens multiple times per session and is disrupting my trading. Can you help identify the cause and a permanent fix? Date Time Of Last Edit: 2026-06-25 17:05:37

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. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Now that we have looked into this. This is next to impossible for us to identify the reason. There could also be a problem in one area of the program causing a problem in another area. Try disabling OpenGL.
