The next time this happens please take a look at the database
header page. (eg. gstat -h <db_name>) This could be a data
issue, db design issue, an indexing issue or perhaps a problem
with InterBase. I don't see the ability of killing the query
as a real solution to your problem because you still want the
query to execute quickly. The ability to kill it in this
scenario would be more of an 'emergency' tactic which may be
a good reason to have the functionality.

Is the printout optimized into a stored procedure or view?

I try to recommend that when persons are 'developing' reports
that they do so on a 'development' server not the live system.
Once satisfied with performance and function, then more the
report into production.

Are the queries optimized with views or stored procedures.
Where they executed with a local connection path.

(eg. connect /db/mydb.gdb vs. connect myserver:/db/mydb.gdb)

Is this the case when the client (gds_inet_server) is waiting
on a resonse from a request or is it just sitting idle maintaining
a connection?
