Bug reference:      2446
Logged by:          Stephen
Email address:      jleelim(at)hotmail(dot)com
PostgreSQL version: 8.1.3
Operating system:   Windows Server 2003
Description:        FATAL: Could not write to statistics collector pipe.
Details: 

I'm getting this error in my logs on all of my servers running Windows 2003
with all the latest service pack installed. 

FATAL could not read from statistics collector pipe: no error

LOG statistics collector process (PID 5732) was terminated by signal 1

FATAL: Could not write to statistics collector pipe.

LOG: could not receive data from client: No connection could be made because
the target machine actively refused it.

I don't know if the last error had anything to do with it. What could be
causing the problem?


I'm attaching the postgresql.conf file below

# -----------------------------
# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
#   name = value
#
# (The '=' is optional.) White space may be used. Comments are introduced
# with '#' anywhere on a line. The complete list of option names and
# allowed values can be found in the PostgreSQL documentation. The
# commented-out settings shown in this file represent the default values.
#
# Please note that re-commenting a setting is NOT sufficient to revert it
# to the default value, unless you restart the postmaster.
#
# Any option can also be given as a command line switch to the
# postmaster, e.g. 'postmaster -c log_connections=on'. Some options
# can be changed at run-time with the 'SET' SQL command.
#
# This file is read on postmaster startup and when the postmaster
# receives a SIGHUP. If you edit the file on a running system, you have 
# to SIGHUP the postmaster for the changes to take effect, or use 
# "pg_ctl reload". Some settings, such as listen_addresses, require
# a postmaster shutdown and restart to take effect.
