postgres server crash

Hi all,

I am running DBT2 benchmarks on a 4 way Win 2003 server when the
postgres server process crashes. Then I tried on a 1 GB P4 desktop
running XP and could reproduce the problem quite often. The error
message is at the end of this mail.

I did the following to dig more into the problem:

* The server crashes with default postgresql.conf parameters
* I tried to get more log info by turned few log params in
postgresql.conf file and ran it for only 1 connection. To my surprise
there was no crash and the entire DBT2 ran successfully.
* Then I started making the log params one by one default so that
I can zero on the log param which is making it pass. I see turning
log_min_error_statement to a debug level is not causing server crash for
1 connection.
* Then I tried to increase the no. of connections to 20 and see
that it crashes always.

I had run the DBT2 tests on the same box on SLES 9.0 without any
problems. Hence I suspect this is a win32 port problem.

It seems the server is crashing on a wait. Anyone else faced this
problem/any reasons for this failure ?
