upgrade as much as possible :) Upgrade the system glib, db2 libraries Upgrade the perl modules, perl DBI, DB2 Install a new perl (don't update system perl ) And try again :)	[reply]

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

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	[reply]

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).	[reply]

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.
