Hi Hsie, Did you make any changes on squall this afternoon? I ask because I am now able to run McIDAS commands with no hangs and earlier today (before 12:45) McIDAS processes were hanging. Our general hypothesis this morning was that there was some resource that was being waited on by McIDAS processes run as you ('hsie'). Interestingly/baffingly the hanging was not see as the user 'ldm'. The only difference I could see in the setup for 'ldm' and 'hsie' was the group that both were in. I am not sure if this could cause resource contention problems, so that was why I said I was baffled earlier. So, if you made any changes on squall today after about 12:45 am, please let me know so I can better understand what was happening. Cheers, Tom **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
