[SOLVED] LXC syslog messages related to different container

[Paspao]

Hello,

I found in syslog of LXC with CTID 121 messages related to other LXC with different CTID :

May 23 12:09:30 dq kernel: [5441664.537117] dump_stack+0x63/0x8b

I do not think this is expected. How can I troubleshoot and solve this issue?

Thank you.

it's normal behaviour to see kernel logs since they share the kernel

Great thank you, one thing less to worry ;-)
