Hi, During the weekend my corosync daemon suddenly died without anything in the logs, except this: May 5 20:39:16 ZZZ kernel: [1605277.136049] traps: corosync[2811] trap invalid opcode ip:5635c376f2eb sp:7ffc3e109950 error:0 in corosync[5635c3745000+47000] The version is corosync 2.4.4-3 amd64 standard Debian stretch Any ideas? Best regards, -- Klecho
