According to the DBI docs "connect" should be returning undef on failure
and should not be causing the script to die. Can you show us some code?
In most cases you would catch an exception (death) caused by a module
using "eval" to wrap the code in a block.
perldoc -f eval
eval {
# code that could fail
die "....";
}
if ($@) {
# handle error condition here, error is in $@
}
