Periodically, the system will crash and halt the CPU with the following message: Machine software error: Protection violation on interrupt stack. AT&T insists that the crash is due to a hardware error. However, this same VAX can run UNIX 4.1BSD and VMS with no problems. Any clues to the cause of this problem would be immensely appreciated. Thank You, mlip@nadc (Michael Lipczynski)
