Unity Server Locks Up

[kc4ixi]

I am installing a MCS 7815 Unity server. The server appears to run fine for a few days and then locks up and I have no video signal and cannot access it at all. Also the hard drive activity light is constantly on and I have to physically reboot it to get it running again. I have already had IBM replace the motherboard and have performed a clean install of OS and Unity and the problem has come back. Does anyone know of a problem that I could check about. After rebooting I get an event log message stating that the previous system shutdown at 1:17 a.m. which the current time is 3:30 p.m. the next day. I'm not sure where to go now.

You didn't provide a Unity version here, back end configuration, switch setup (i.e. are there Dialogic cards installed) or much else to go on but regardless I don't know of any known issues for any recent versions of Unity that would explain this type of hard lock...

This isn't something we'll be able to troubleshoot out on the forums terribly well - you'll want to open a TAC case ASAP if you haven't already.
