in reply to glibc detected error with sth->{db2_more_results}

Provide the output of uname -a and the version numbers of glibc, Perl, DBI, DBD::DB2 and the db2 client library you are using.

    Linux 2.6.18-128.1.6.el5 x86_64 x86_64 x86_64 GNU/Linux
    PERL : 5.8.6
    db2cleint: 9.1
    package Bundle::DBD::DB2; $VERSION = '0.78';

      perl 5.8.6 released 2004-Nov-27

      DBD-DB2-0.78 released 19 Sep 2004

      At a minimum you should upgrade DBI, DBD::DB2 as well as all other installed DBI/DBDs

        tested on older version of linux with same set of perl,dbi and db2client. it works fine.

      That "double free or corruption" error is coming from glibc. Means that one of your libraries is doing a double free on some variable somewhere. There's little you can do except find a version where that bug doesn't happen, or file a bug with the author of the problematic library (probably one of your database libraries).

        Oh, forgot to mention: You can suppress that check with the environment variable MALLOC_CHECK_=0, but it's still a bug in one of your libraries and you are likely to crash sooner or later. GlibC's default behaviour is just to stop immediately.

      sorry forgot to add glibc version

      Name : glibc Version : 2.5 Vendor: Red Hat, Inc. Release : 34

      You really want to upgrade if possible. To quote Dr. Jones: "It belongs in a museum".

      Apart from the problem you described, there are probably a zillion other critical bugs in your system that have been since fixed (and, as a bonus, you'll get a bunch of new ones installed when upgrading).

      The problem is, most - if not all - of the software you mentioned seems out of support. Meaning, you won't get critical bugfixes, which in turn means you might have a security problem.
