Our HP 9000/425 server with HP_UX 8.0 crashed twice in a row today. The first time it crashed the message "panic: free: freeing free block" was displayed. Then, while /etc/rc was executing during bootup, the system crashed once again with the message "panic: ialloc: dup alloc." The system worked after rebooting on the second attempt.
Could someone tell me what these messages are and how they can be prevented?
