web page generation hangs

[Jason Friedman]

I'm using Perl 5.8, Postgresql 7.2.2, and Apache 2.0.40. I'm using
mod_perl, but the behavior is the same if I turn that off.

I have a link to a Perl script, the script uses the DBI to pull data
from the database and output HTML. I've done this hundreds of times
over the past couple of years, it works great. Click on the link and
generate the page.

I have a problem with one page, though. The query brings back 50
rows. I watch the DBI log file and the Postgresql log file: postgres
is pulling all 50 rows, but DBI seems to stop at 17 rows! My web page
never gets generated. If I add LIMIT 15 to the query, both log files
show 15 rows retrieved, and the page comes up fine.
