I have been using LXD for a while now, and not had any major issues. Recently (a few months now), I have been having the below error
Error: Failed to retrieve PID of executing child process
but haven’t spent time collecting logs or debug until now (rebooting my host or lxc stop/start has normally resolved it for me). I have looked through the forums, and seems there are a few people who had similar issues, but doesn’t seem like any of the resolutions seem to help with mine.
That’d be one for @brauner but it sounds like it may be cgroup related.
The raspberry pi kernel comes with the cpuset and memory cgroups disabled by default. I don’t know if it’s related, but maybe enabling them (done through a kernel boot parameter) would work around this issue?
no luck I’m afraid, (but that addition has fixed my other issue with my MAAS in LXC)
at 15:38 localtime, there as a termination signal, not sure why, and how, the first pastebin shows that. Maybe this is the time when it is causing this potentially (I was doing an lxc exec randomly during the day with success, until now)
I tried manual refreshes, but didn’t get the same logs from before, as that just restarted all the containers. So it was weird to see, and may have been a one-off, and probably going to ignore until I see it again.
