I've just taken our name server down for maintenance, and noted that a
db-aware app I'd left running ground to a halt despite the fact that it
was only activating queries, not establishing new (named) connections.
The connection was being made by host name rather than by dotted-quad
address, resulting in a long-term handle associated with the
TPQConnection object. Whenever a TSQLQuery is activated, it results in
the opening of a short-term handle, if I'm reading things correctly
associated with a TSQLTransaction object which relies on the host
information from the connection object.
My expectation is that these short-term handles should not mandate a
name lookup, since the host name or address cannot be specified at this
point. Am I being unreasonable?
