The RAM looks bad. I test all my servers with these userland programs: redis-server --test-memory 4096 memtester 4096 1 Redis test: I run the test few times, some times it show error and some times it show i= t is ok. But I am not sure how reliable is the redis-server test and if it locks= the RAM before it does the tests. Memtester: In the server that panic yesterday the "Bit Flip" test shows issues. Also in another server tests show "Solid Bits" and "Bit Flip" issues. As these 2 servers are old I will replace them this week with new hardware. --=20 You are receiving this mail because: You are the assignee for the bug.=
