[otrs] Errors from CRON jobs about DB.pm...

This is one of the many errors that our install of OTRS is generating right now. Initially, this type of error hasn't occurred for past few months that OTRS has been installed. For the last couple of weeks, it has been generating the messages like the ones pasted below each time a CRON job runs. So far I have not been able to determine the cause. The only change we've made around when the error messages began was to configure the apache server to use a "virtualserver" for this domain. This is installed on a red had dist. Of Linux, using mostly default configuration options (save for the change in apache mentioned above.) Redhat 9, MySQL 4.0, Apache 1.3, PHP 4.4.1 Has anyone else encoutered this type of message before - and how did you fix it? Below are a few examples of the error messages I've been receiving (I've noted the 'subject' and 'body' of the messages below.) Thanks Eric N ---example 1--- Subject: Cron $HOME/bin/GenericAgent.pl -c db >> /dev/null Body: DBI::db=HASH(0x8adac60)->disconnect invalidates 1 active statement handle (either destroy statement handles or call finish on them before disconnecting) at /opt/otrs/Kernel/System/DB.pm line 219, <PRODUCT> line 4. ---example 2--- Subject: Cron $HOME/bin/UnlockTickets.pl --timeout >> /dev/null Body: DBI::db=HASH(0x8af1704)->disconnect invalidates 1 active statement handle (either destroy statement handles or call finish on them before disconnecting) at /opt/otrs/Kernel/System/DB.pm line 219, <PRODUCT> line 4. ---example 3--- Subject: Cron $HOME/bin/PendingJobs.pl >> /dev/null Body: DBI::db=HASH(0x8aef6a8)->disconnect invalidates 1 active statement handle (either destroy statement handles or call finish on them before disconnecting) at /opt/otrs/Kernel/System/DB.pm line 219, <PRODUCT> line 4.
