Issue resolved. The source of all trouble was that the Scheduler uses the
same db connection as the task it executes. Thus output updates (print
'!clear!%(progress)s' % progress) changes the connection status, randomly,
hence the strange exceptions.
Suggestion: explicitly mention this as a
How about generating most of the pages and serving them as static content
(e.g. templates that have nothing to render, just plain HTML); then having

processed (e.g. a contact form + a POST handler) ?

Hello all,
I follow a simple video-tutorial (http://vimeo.com/27478796); so I create a
model scheduler.py with this content:
def f():
t = time.ctime()
open('/tmp/tasks', 'w').write(t + '\n')
return f
from gluon.scheduler import Scheduler
Scheduler(db, dict(our_func=f))

Niphlod, yes, that was it !!
It was not in the db.py but there was a 0.py with 'settings.migrate = True'
(this is not my app, I was just asked to hack there to fix an issue).
An easy workaround might be to also set fake_migrations to True
(fake_migrate_all=True in DAL() creation) and copy and
Leonel, thanks so much for the advice!

Thanks, Massimo! I upgraded to 2.8.2 with minor issues (MySQL date fields
seem to have been mapped to strings and now to datetime
Massimo, thanks a lot for your help!
I will upgrade right away then. (I have very limited time, so I was afraid
