Hello all,

previously posted to pgsql-bugs:
http://archives.postgresql.org/pgsql-bugs/2003-03/msg00209.php

As it didn't get much traction there (since the bug does appear isolated to
cygwin; race condition in cygipc?), is anyone here able to:

a) replicate the problem on their system?
b) confirm our suspicions of cygipc (and/or point us in the right direction
for correcting the culprit)

Cheers,
Claudio

Hello,

> a) replicate the problem on their system?
I've reproduced it
on

Win2K (SP3)
cygwin 1.3.21-1
cygipc 1.13
postgresql 7.3.2-1

It hangs after about 1000 create/drop pairs.

> b) confirm our suspicions of cygipc (and/or point us in the right
direction for correcting the culprit)
I'm sorry, I could help any further.

By,
Joerg.

Of course, I wanted to say "I could not help any further",
but now I found that not only psql hangs.
It seems, that ipc-daemon hangs too.
Nor I can't start postmaster again,
neighter I can't leave the sesseion where
ipc-daemon runs (with Ctl-D).
Only "hard" close of window worked.

I know, it's not a big help, but it also points to cygwin/ipc.

By,
Jörg.

Unfortunately, I think that the following applies:
