Issue

A core dump is captured due to a controller panic with the following exception:

---- Log Entry #3 (Core 0) MAR-08-2018 10:14:50 AM ---- 03/08/18-10:14:50 (raidSched1): PANIC: PRES: peering discrepency SSID: 0x3 IpID:0xe TpID: 0xa  

During the time of the first panic, the alternate controller panicked as well due to an ancient IO detected without generating a core dump:

---- Log Entry #3 (Core 2) MAR-08-2018 10:19:50 AM ---- Reboot due to ancient IO, scsiOp=0xffff800004d392e0 poolId=0 opCode=5f age=300023ms
