Another observation that i considered bad news is that all

Well that's rather bad. AFAICT most of the allocations in there are
GFP_KERNEL, so why is this happening?
Need to trace the cause.
Because the kernel is producing netlink messages faster than userspace can
consume them, perhaps?
Hmm...possible. A quick check would be to reduce the frequency of exits
and see.
If so, the sender needs to block, which means we
need to make reception of these stats a privileged operation?
Won't it suffice to make delivery of these stats best effort, with
userspace dealing with missing data,
rather than risk delaying exits ? The cases where exits are so frequent
as in this program should be
very few. Making the reception privileged would kind of constrain the
utilization of stats and I'm not
sure if its warranted.
