[14:38] Hi Everyone. I'm testing out Ubuntu 21.10 in an Azure cloud VM. My SSH connection drops out quite frequently and the VM appears to be unresponsive when I try to log back in. [14:38] I've been mainly looking into /var/log/syslog but wasn't sure if there were other areas to investigate. Any suggestions as to what events I should look for in any of the logs to diagnose the issue? [14:47] It just happened again. Had to invoke , `~` and then `.` to kill the SSH session. [14:47] When I try to SSH back in, nothing happens [14:50] The serial console within the Azure dashboard is also unresponsive for this VM [17:41] maybe a kernel/virtualisation issue? [17:42] are you using the Azure-specific kernel? [17:43] JanC: Sorry for the dumb question but can I get that information from `uname -a`? [18:06] output of `uname -a`: 5.11.0-1013-azure #14+21.10.1-Ubuntu SMP Mon Jul 26 12:43:33 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux [18:07] looks like that is the azure kernel indeed
