I got the following error this morning from the console on one of our JS21s. I had a program that was supposed to ssh into the blade and reboot it after shutting down GPFS. I don't think it did any of the gpfs shutdown before crashing. Here is the error message. I saw it because I happened to be on the SOL console ( I wouldn't normally be). This is the first time I'm noticing this. I will post again if I see more errors of this kind.
