Hi all!
I've experiencing this problem for some time now and even after
debugging, i could not find why it happens.
I have a medium sized multi-thread application that manipulates
SQLAlchemy objects - the objects are passed from thread to thread, so,
when i load an instance i close the session.
After working on the object, i need to update the status of the it, so
i do something like this:
job.status = FINISHED
session.add(job)
log.info("Finished job %s" % job.filename)
session.flush()
This code works pretty well, but from time to time, i get this on the
logs:
"UnboundExecutionError: Instance <Job at 0x413ee50> is not bound to a
Session; attribute refresh operation cannot proceed"
The complete stacktrace is here: http://pastebin.org/54196
Could this be happening because of my pool_recycle setting (300
seconds) ?
