Bug : unable to increase the number of client

Hi all,

I'am trying to tune the configuration of PostgreSQL 7.1.3 under Windows
2000 with Cygwin 1.3.10
I want to test the installation pgbench

All is approximately OK up to 25 clients.
For a number a litle bit larger of client, I get a fatal error reported in
the next log file (See attached file: FATAL.LOG)

2002-02-22 07:03:13 [1776]   DEBUG:  query: insert into
history(tid,bid,aid,delta,time) values(10,1,70266,193,'now')
/usr/bin/postmaster: reaping dead processes...

For a larger number of client, Windows 2000 is unable create all the needed
backend (See attached file: FORK_F~1.LOG)

/usr/bin/postmaster: BackendStartup: fork failed: Resource temporarily

Backend startup failed
pq_recvbuf: unexpected EOF on client connection

The max_connectionsparameter is set to 200. The PostgreSQL configuration
file is (See attached file: POSTGR~1.CON)

and the cygwin diagnostic file (See attached file: cygwin_conf_diag.txt)

Any help would be very strongly appreciated
