@Tomas: what can you reproduce exactly? The rapid system wakeup events or the strace output with the pselect6 calls specifically?
@Colin: how did you capture that strace? On my Hirsute system I tried $ sudo strace -fp <containerd pid> -s 1000 and I can see a lot of events but not the pselect6 calls, see [1] for my strace output. I *do* see a high number of wake events using eventstat and I agree with mwhudson in that we should probably report this issue upstream, however let's try to get a solid reproducer first.
