@phausman thanks for the update! To be more specific, it would be interesting to take a look at dmesg while the problem is happening (I would expect to see a kernel oops: hung task timeout). It would be also interesting to take a look at the parent of these zombie tasks and try to figure out if it's stuck somewhere (cat /proc/<pid>/stack).
