Memory allocation and Vacuum abends

Hi all,

I have a 4 CPU, 4GB Ram memory box running PostgreSql 8.2.3 under Win 2003 in a very high IO intensive insert application.

The application inserts about 570 rows per minute or 9 rows per second.

We have been facing some memory problem that we cannot understand.

From time to time memory allocation goes high and even after we stop postgresql service the memory continues allocated and if were restart the service the Postgres crash over.

It's a 5 GB database size already that was born 1 and a half month ago. We have 2 principal tables partitioned.

Above is the log file. Do anyone have any idea what could the problem be......

Thanks in advance.
