[Spacewalk-list] rhn-clone-errata.py ProtocolError:502 -ProxyError

[Jet Wilda]

That is what I'm starting to think (database slow).  Once we have this
moved to our new setup I'll report back if I still see this error.
Thanks

To Justin's point, I had this exact problem when I was working on this
initially.  The API function: "server.errata.create" takes a boolean
parameter for publishing during errata creation.  I found that if I
combined publishing with errata creation that I would get intermittent
timeouts, it was just taking too long to complete the operation.  I
decided at that point to handle the publishing in a separate call and
that seemed to help.  I don't believe that I've run into this issue
since then.

Also, I have most of the functions in this script automagically retrying
4 times (I believe)... before a fatal error occurs.  This should cover
any random intermittent tomcat/apache communications problems.  I can't
think of anything right off that I can do to make this even more
forgiving.  Perhaps there is some tuning that can be done to increase
the timeout between tomcat/apache.  Perhaps your underlying Spacewalk
database is slow?
