Thanks for the file. We haven't been able to reproduce the failure
yet, but we'll keep you posted. (Any server config etc. that's worth
knowing?)

Until we know more, the first workaround I can think of is to increase
omero.sessions.timeout. See:

    https://www.openmicroscopy.org/site/support/omero5.2/sysadmins/config.html#omero-sessions-timeout

Compared to other pyramids you've generated, how long would you
*expect* this to take?

Cheers,
~Josh.
