Обсуждение: COPY problem
I am creating a new database on a brand new server (P4, 1GB RAM, postgres 7.3.3, debian 3.0) and trying to populate one of the tables with the COPY command. I split a large file with 20 million records into 20 files, but when I run COPY I usually get the following message: analytics=# COPY tbl555 FROM '/usr/local/pgsql/xaa' WITH NULL AS ''; ERROR: copy: line 167641, Query was cancelled. The line number varies each time I run it, and occasionally succeeds. I split up the data into even smaller files (100,000 rows) with the same results. Then I tried it on one of our older debian boxes (version ?) with postgres 7.3 and the COPY's succeed. I turned up logging on the new server but the messages returned are: Jul 16 09:04:43 imp postgres[31180]: [72-2] Free/Avail. Space 0/0; EndEmpty/Avail. Pages 0/0.

I am thinking that it may involve one of the following, but am not sure which: - my configuration file changes - ram - driver issues - mother board = asus p4 p800 - driver issues - hard drive (IDE) - ? Thanks in advance Ron

I was testing a Linux distro recently and gave /usr lots of space, forgetting that Linux distros often install postgresql and mysql to /var/db (or /var/lib/db -- I forget). If this is your problem (and you don't want to reinstall Debian), stop the database server, move the postgresql directory to a spacious partition, and create a link to it in the original location. Best of luck, Andrew Gould

"Query was cancelled" is not a failure that the database would ever
produce on its own. Something external to the Postgres code decided
to send SIGINT to either psql or the connected backend.
I suspect that you are running into some kind of resource-usage-limiting
functionality that you were not aware was active. Perhaps you have
"ulimit" settings that are restricting how long a process can run or how
much I/O it can do. It's a really bad idea to start the postmaster with
any non-infinite ulimit settings :-(. ulimit on the client side is not
so dangerous, but could still prevent you from getting your work done,
as in this case.
