Pulp produced truncated iso file during publish of export distributor because of not enough space in working directory.
We were publishing 38 repo groups - 38 publish operations were started and then one big join() for all of them.
Errors that were produced during publish:

Beacuse of retries in our publishing systems, all publishes eventually succeeded. Next step was to synchronized published repositories back to pulp. It failed with

I think this could be related to https://pulp.plan.io/issues/2142
