Should have posted to users not dev. This is really a bizarre problem.
I can get it to fail about every fifth iteration otherwise the process
works. I ran it from another server connect to the same database and
it will intermittently fail. I run it from a third sever and I can't
get it to core dump. All 3 servers have the same kernel & Perl
versions. I've tried recompiling Perl, DBI, DBD::Oracle, still no luck.
I created a test case, which uses execute_array and of course I can't
get it to core dump. If anyone has any ideas on what might be going on
here, I would love to hear them!
Thanks
