Folks: Beginning in March, I've seen a dramatic rise in the number of complaints among my users. The main gripe is dropped connections: sometimes after 2 minutes, sometimes after 5, but usually before 10 minutes. I have been monitoring the cards and watching connections come and go, but cannot seem to put my finger on any one piece of equipment. The nature of the problem is both random and intermittent: two of my favorite things. Has anyone else had a problem with this? We currently running: HiPerNMC: 8.2.96 HiPerARC: 5.2.9 HiPerDSP: 3.1.7 and I plan to upgrade this week to HiPerNMC: 8.6.3 HiPerARC: 5.3.110 HiPerDSP: 3.5.109 Any clues? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Michelle Mogil, mmm3@cornell.edu Information Technology Engineer Systems & Operations, CIT Cornell University, Ithaca, NY 14853 USA vox: 607-255-0516 fax: 607-255-8521
