This is on 8.3.8, latest Ubuntu distribution, server under quite heavy load.
afterwards we had some corrupted pages ("ERROR: compressed data is corrupt").
Random segfaults only under heavy load with corrupted pages afterwards normally means bad RAM. I'd suggest a round of memtest86+ on the system if it's PC hardware.
