check errpt if you were maybe running out of pagingspace of if you exceeded the maximum allowed pinned pages.

If you are running a cluster, it may be the cluster software or application that caused the reboot - Oracle rac tends to occasionally boot a node or both in case of various problems like lost heartbeat or major application issues - hacmp does similar things.

Another possibility is that you are facing problems on the hardware (like memory or cpu errors on the frame itself) which may cause the frame to reboot your lpar to free up the faulty resources.

Kind regards
