Hi there,
Replying to [comment:193 jdemeyer]:

'''something''' goes wrong.
Unfortunately the one week window for sage days I had is over. I didn't
had
time to make any experiment, and I don't expect to find much time to work
on
this in the forthcoming days (the new semester is starting and I'm moving
from
one house to another in two weeks).
Anyway, I have a guess one what could be happening. The first pass of
compilation is designed to build the intersphinx inventory. However, they
are
rewritten during the second phase. Due to parallelism, it is fairly
possible
that one process is trying to read the inventory just at the time another
one
is writing it. The more process you have, the larger the probability of
this
happening. This explain why we don't see this on small laptop. I'm not
sure
how to test that this is precisely what's happening. But if it's the case,
the
solution should be easy: similarly to what I did recently for indexes, we
should deactivate the output of the inventory for a second pass
compilation of
a sub-document.
Does anyone have time to experiment more ?
