invalid memory alloc request size 1684370054

[Brendan Duddridge <brendan@xxxxxxxxxxxxxx>]

Hello,

Today in our logs we received the following exception:

Exception Message: EvaluateExpression failed: <com.webobjects.jdbcadaptor.PostgresqlExpression:

update category_product

set product_is_active = p.is_active, product_status_code = p.status_code

from product p

where category_product.product_id = p.product_id  and

category_id = 1001415;

Next exception:SQL State:XX000 -- error code: 0 -- msg: ERROR: invalid memory alloc request size 1684370054

I'm not sure which memory setting I need to change to correct this. I have the following postgresql.conf settings (that are changed from their defaults) on an OS X Server 10.4.6 Xserve with 8 GB of RAM:

max_connections = 100

shared_buffers = 4096

work_mem = 4096

maintenance_work_mem = 32768

max_stack_depth = 6144

max_fsm_pages = 300000

wal_buffers = 64 

checkpoint_segments = 128

effective_cache_size = 655360

default_statistics_target = 100

stats_start_collector = on

stats_command_string = on

stats_row_level = on

autovacuum = on

statement_timeout = 180000

deadlock_timeout = 3000

Do these settings seem reasonable for an 8 GB machine?

The update was operating on a category that has 113,299 products in it.  I'm guessing that blew some memory gasket somewhere! :-)

Thanks,
