WARNING: dup(0) failed after 3195 successes: Bad file descriptor

Hello list,

I'm just reposting this question, that didn't get feedback a few weeks ago.  I 
can't for the life of me guess why I'm getting this error in the logs when the 
postmaster service starts.  I've got it running in cygwin on XP Pro (SP2), 
originally with ipc-daemon, now with cygserver.  I've seen similar postings 
about this answer, but I can't tell if anyone has actually resolved it...

A better description of what I've done to try to fix this is below...

Any guesses/suggestions?

Thanks,
Mike

Hello list,

I'm getting this error as well.  I'm running XP Pro, with SP2 (RC2).  Until 
just now I had PostgreSQL 7.4.1.  As far as I could tell, everything was 
running fine...then as I was updating some tables I started getting errors 
(sorry I didn't record them).  I had my whole database backed up, so I tried 
to delete the database using "dropdb" so I could reload the backup, but the 
dropdb command just hung there and did nothing...

I tried cleaning out the whole PG data folder, and reinitializing.  It seemed 
okay...I could run "createuser", but it hung again with "createdb".  Next I 
installed PostgreSQL 7.4.3.  I got through the setup okay, and the services 
appear to be running fine, db initialized okay, and I could create new users 
as before, but the postmaster.log still has the same "dup(0)" error, and it 
still hangs if I try to create a database.

Earlier this week I installed the second release of XP SP2 - I suppose that 
could have something to do with it.  Did the others with this error find a 
solution?

Kind regards,
Michael Leahy

AFAICT, no.
