The iop models on h1seih(23, 45) went into a DAC+DK error state this evening. This is covered by the FRS opened for this morning's 03:29 event FRS11680
Before restarting the models, I captured the /proc/h1seih(23,45)/status files (and tailed the dmesg). The models were restarted using the /etc/startWorld.sh script.
If this problem persists, we should consider a power cycle of the IO Chassis. It is not clear how h23 and h45 are paired, I'll take a look at the Dolhin IPC table.
