Hi all:
I'm not sure if this is specifically a python problem or a larger
underlying memory problem. Since upgrading to Python2.6, we have not
yet gotten owfs working again. This most recent test was from a
2.7p2x build and python 2.5. The second snippit is from 2.8p2 and
python 2.6.
We burn a brief ID into our 2406's for our software to identify what
type of device it is. We use XML as much of our data elsewhere is
xml:

Note that the XML on the second one, the leading < has become a 0.
That appears to be what's breaking things currently. Any ideas what's
causing this and/or how to fix it?
Thanks!
