OI MBTCP crashing

Flix Deblois Leclerc

Hi , we currently have intermittent issue with the OI MBTCP. The version is 2023.1 Patch 3 but the issue is happening since 2020. 

We have 8 Schneider momentum CPU and 1 Schneider M340 CPU.  The OI seems to drop and we have to restart the computer to have it to work again. At first I was thinking it was because of the mix of momentum + the M340 so we created an other instance of the OI only for the M340.

Last time we had the issue the OI for the momentum crashed but the one for the M340 stayed up. The issue is really random and hard to troubleshoot since its only happening twice a year...

Since the update to 2023.1 Patch 3 im seeing the following message in the log. I dont know if this can be part of the issue.

    Hi Felix,

    This seems like something for Tech Support to look at, so I recommend raising a service request if you haven't done so already.

    That warning message seems like a solid clue so please include that in the service request. We definitively want to improve on the driver to ensure that it deals gracefully with possible buffer overflows (or any other issue for that matter).
