Oh yes, I figured that. Each thread in this application opens its own
connection, so this ought not to be the issue. Each DB insert actually gets
the data into the table, but 2 of the 3 threads stop after that... possibly
due to concurrently accessing sections of the sqlca struct? (that's just a
guess though)

Our code is a bit tricky to get running - I might see if I can create a simple
test harness to duplicate the problem and post it to you.

Regards, Philip.
