 - Probably a bug ; have a try with https://software.cisco.com/download/home/286286911/type/280805680/release/15.2.8E5
                                                             (current advisory release and check if that can help_

I have an architecture with several IE5000 in STACK configuration and no problem on my 4 other networks. All my STACKs have the same version 15.2(7)E.

 - Usually that is to be 'excluded' from the solution offered ; meaning that particular bugs can also be triggered on device specific load , specific networking patterns traversing it  , ...(e.g.)

The only thing that's different from other switch stacks is that this network is in RTSP, while the others that don't show the error are with REP protocol.

Thank you for your reply. I am going to install version 15.2.8E5 for the two switches forming the STACK (IE-5000-12S12P-10G Industrial Ethernet Switch).

The network is in operation, I need to arrange a shutdown with the customer to install the new firmware. This will not be done now.
And the problem is that at some point, about 8 weeks from now, one of the two switches restarts by itself.
