Hello.

Actually this is complaints about no disk space (28 == ENOSPC).
And your free disk space looks far from being exhausted, right?

I think this is other side of the problem I have announced
(leak of disk space related to tail conversion). Unfortunately,
I have lost the scenario for reproducing this problem.
Will go to todo-list.

Thanks,
Edward.
