I have an appliance hosted on pythonanywhere which uses the Scheduler 
(invoked using a separate web2py process with the -K switch).

This setup in my test environment (OS X at home) works fine, but on 
pythonanywhere, the scheduler process generates a stream of errors like:

ERROR:web2py.scheduler.giles-livetask2#30970:Error coordinating TICKER
ERROR:web2py.scheduler.giles-livetask2#30970:    error popping tasks

Attempts to schedule a task fail to even have a new task record inserted, 
much less executing that task.

It was working a week ago.  I thought it might be due to upgrading to 
2.14.6, but the last successful tasks show 
"web2py.scheduler.giles-livetask", so maybe the problem came after that 
upgrade.

I thought maybe the scheduler database was corrupted, but I can view the 
records via the admin appliance.

Any suggestions as to what I should investigate next would be appreciated.
