I have many internal systems which use Apache::DBI and DBD::DB2. They're often up for months without being restarted, and I don't use ping(). So, it is possible. Are you the DBA too? A possibility is that the DB is being brought down into offline mode during the night for backups. That'd kill your cached connections. I'll send a fuller answer when I have a chance to reexamine our set up. Bill
