Hi Wally, Thanks for the suggestion. Here's what I've currently got configured:
MSGTQL is set to 1024. ipcstat -qon shows nothing ipcs -qop shows 5 queues (0-4) all with 0 in the CBYTES and QNUM columns I ran udtconf & allowed it to autoconf, then rebooted the system. So far (knock on wood) we haven't had another hang, BUT I have all of the cron jobs that start Unidata phantoms temporarily disabled.

The installation (fresh installs of both) went smoothly, and everything seemed fine after the upgrade. This morning, however, once all of the users logged in, they are intermittently experiencing "hangs" (i.e. no response from their terminals). Unix is still up and running fine, but the Unidata sessions can't be killed using stopudt pid. They CAN be killed using kill -9, but a 'listuser' shows them as still logged in to Unidata. The hang affects ALL Unidata users. If I attempt to begin a new Unidata session, it starts, but immediately hangs. I'm not seeing any obvious problems in the Unidata log files. The hang may or may not be related to a couple of cron jobs that we have running once per hour. After the last two, I noticed that there were PHANTOM users in the listuser output. There were no errors in the _PH_ output files or the log files that the PHANTOM jobs created. All of the kernel tunable parameters are set at or above recommended settings (I can provide the config settings if needed). Any ideas?
