system hang

[SIMSN%NUSDISCS.BITNET at cunyvm.cuny.edu]

 We're running Sys V 3.1.1 on a AT&T 3B4000/15. Lately we're experiencing
 some hangup with our system without any warnings nor error message on the
 console.

 One moment it was running well and the next it just went down to IAU
 mode. We did the normal dgn and the system came up normally.

 Any comments??

 Thanks.
