That certainly makes not much sense. I haven't seen any of these problems. To 
me, this looks like either you run out of disk space (or disk quota, if your 
system administrators impose one), or indeed some instability of the cluster.

I know this is not a satisfactory answer for you, but I would suspect that you 
would have these same problems with any other parallel code you run there. 
Nothing of these error messages seems to me to be specific to ASPECT :-(
