Re: Crash of Postgresql on Windows - Mailing list pgsql-general

Hello,

I am sending this email since I am hitting a snag with postgresql. I
am currently running the following version of postgresql:
Postgresql 8.3.5 on Windows XP Pro 32bits

I am getting a crash whenever I try to perform an update on some rows.
More precisely, I have recently imported a dataset and managed to work
through it easily. However, when performing one update I am getting
the following error:

GMT PANIC:  could not write to log file 40, segment 44 at offset
8929280, length 1744896: Invalid argument
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

I am a bit lost on what to do next. I have tried running the query
several times even changing the parameters to make sure if it wasn't
something in the sql.
UPDATE gtable AS g
      SET     code = '00' -- 04
      WHERE   g.code = '04'
              AND g.cc = 'TW';

UPDATE gtable AS g
      SET     code = '00' -- 04
      WHERE   g.d IN (6724652, 1673813);

Those two queries do exactly the same thing but they both crash with
the same information, except for the length between the two queries.
What should I do?
