Howdy,
Environment:
Postgres 8.3.13
Solaris 10
I have a SELECT query that runs no problem standalone but when running
within a perl script it intermittently core dumps. Random, no pattern
to the timing of the core dumps. The perl script processes the rows
from the query, if the rows satisfy a condition then the perl script
adds the rows to another table. When the script works it runs for
about a minute. If the script fails, it runs for about 5 minutes and
core dumps. The core dump is in the perl error handling routines. We
suspect the bug is related to how the perl postgres libraries interact
with postgres.
The query:
SELECT pa.tag,
pa.name,
pa.notices_sent,
pa.parent,
pa.contact,
pa.adsl_type,
pa.adsl_order_state,
pa.adsl_line,
pa.adsl_site_address,
pa.subnet_addresses,
pa.plan, pa.username,
pa.product_type,
pa.framed_routes,
c.tag,
c.contact,
c.name,
c.customer_type,
pa.technology,
pa.carrier,
pa.dependent_services,
pa.provisioning_email,
pa.provisioning_mobile,
pa.ull_termination_cable,
pa.ull_termination_pair,
pa.ull_termination_terminal_box
FROM personal_adsl pa,
client c
WHERE pa.parent = c.tag
AND pa.adsl_migration_id is null
AND (pa.change_to not ilike '%IBC%' OR pa.change_to is null)
AND pa.adsl_order_state in ('Confirmed', 'Churn-Ordered', 'Provisioned', 'Held')
AND (pa.adsl_type <> 'IBC' OR pa.adsl_type is null)
AND pa.active in ('Active', 'Pending')
AND (c.contact not ilike '%noncontact%' OR c.contact is null)

pa.notices_sent not similar to '%(Confirm|Provision)%') OR
(pa.adsl_order_state = 'Provisioned'AND pa.notices_sent not ilike
'%Provision%') OR
(pa.adsl_order_state = 'Held' AND pa.notices_sent not ilike '%Held%')
