IOP model for h1seib1 modified to permit 10 Dolphin IPC errors per second

WP 3589

I modified the IOP model for the BSC1 SEI system (h1seib1) to permit up to 10 IPC receive errors per second from the h1iopsusb123 sender (SUS ITMY). We are currently experiencing about 5 errors per day on this Dolphin link, we currently dont know what the problem is. We hope the upgrade to RCG2.6 will resolve this issue.

I did a cursory test of the IPC watchdog by PANICing the SUSB123 DACKILL and verifying that the SEIB1 tripped. It is not possible to test that an error rate of >10 will trip SEIB1 without rebooting the SUSB123 and possibly disrupting the mode cleaner work.

We had a single IPC error this afternoon and the SEIB1 IOP ran through it without DACKILL'ing the ISI. So far, so good.
