[7.1b6 on win2k] server crashes with mmap error

Hi all,

tried to install v 7.1 beta6 on a system with following setup:

- Windows 2000 SP1 (384MB RAM is enough even for Windows)
- Cygwin 1.1.8, gcc-2.95.2-6
- cygipc 1.0.9 (took binary, installed it as a service)

I compiled and installed PostgreSQL as a user with administrator
privileges. I also installed a new user postgres, (both Win and
cygwin), and failed when trying to initialize db as postgres:

$ initdb -D /usr/pgsql/data
This database system will be initialized with username "postgres".
This user will own all the data files and must also own the server process.

Success. You can now start the database server using:

/usr/pgsql/bin/postmaster -D /usr/pgsql/data
or
/usr/pgsql/bin/pg_ctl -D /usr/pgsql/data -l logfile start

Well, that's what pgsql said. Tried running it in the background or
foreground to no avail:

postgres(at)ABSOLUT /usr/pgsql/data
$ nohup /usr/pgsql/bin/postmaster -D /usr/pgsql/data < /dev/null
>>server.log 2
>&1 < /dev/null &
[1] 1048

postgres(at)ABSOLUT /usr/pgsql/data
$ D:\cygwin\usr\pgsql\bin\postgres.exe: *** recreate_mmaps_after_fork_failed

[1]+ Exit 1 nohup /usr/pgsql/bin/postmaster -D
/usr/pgsql/data
</dev/null >>server.log 2>&1 </dev/null

postgres(at)ABSOLUT /usr/pgsql/data
$ postmaster -D /usr/pgsql/data
D:\cygwin\usr\pgsql\bin\postgres.exe: *** recreate_mmaps_after_fork_failed
postmaster: Startup proc 1144 exited with status 256 - abort

Also tried it as the user who compiled and installed the stuff, but the same
error occurs. What's going wrong here?

And: how can I install a hopefully running postmaster as a service?

Thanks a lot,
