Perhaps another remnant of last night's model crash (since other Guardian Nodes were found to be Stalled by Ed & Cheryl), but Keita found the SUS_OMC guardian node in the STALLED state (see attached). 

To get it "un-STALLED", I first tried an INIT, but this didn't change the state.  Keita then took the node to MISALIGNED, and this removed the STALLED bit.  He then took the node to ALIGNED, and it was back to a nominal state. 

NOTE: If you are searching for STALLED Guardian Nodes, the easy way to do a quick scan is to bring up the Guardian Overview and then for each node, if the 3rd "State Word" from the left is not-GREEN, then you have a Stalled Guardian Node.   We have no more Stalled Guardian Nodes now!  :)
