Hi all,

I've been working on an application that need to import about 47000
nodes (including relations) and apart from taking quite a long time to
import all of them (about 1 hour on a dual 1Gz PIII machine) I sometimes
see the following or similar errors in the mmbase log:

mmbase.module.database.MultiPool - KILLED SQL SELECT * FROM install_link
WHERE number=1241 time 1040233606 because it took too long

mmbase.module.database.MultiPool - KILLED SQL INSERT INTO
install_categorylink (number, otype, owner, snumber, dnumber, rnumber,
dir, longname) VALUES (?, ?, ?, ?, ?, ?, ?, ?) time 1040058537 because
it took too long

We are using a Postgresql 7.2.1 database. After some tuning of the
database the amount of errors went down to about 1 to 2 errors per
import when the machine is not doing anything else (and we gained about
5 minutes import time :-) 

I've got 2 questions:

1. Will this make the imported data inconsistent?
2. Is there a way of changing this behaviour i.e. by upping the timeout
interval or switching timouts off?

Thanks for your time,
