The following bug has been logged online:

Bug reference: 1451
Logged by: Kim Hansen
Email address: k (AT) oek (DOT) dk
PostgreSQL version: 8.0.0 (MSI)
Operating system: MS Windows XP Pro
Description: FATAL: could not reattach to shared memory
Details:

postmaster.exe did something wrong when it started and because of that it
didn't accept any logins, it used more than 100MB RAM (of 512MB) and it use
100% cpu.

The logfiles were filled very fast, 10 MB where genereated every 22 minutes.
I have attached the first 150 lines of the first logfile created when the
server started to the end of this bug report.

The server stopped without problems when I used the 'Stop Service' program.
I tried to reproduce the problem by stopping and starting the server 5
times, but it didn't reappear.

I hope you can use this bug report.
Regards,
Kim Hansen
