  • Business Automation 7.0
  • Business Automation 7.1


On the installations with the Billing Application node running RHEL/CentOS 7, the To (and in some cases From) field of a notification message may remain empty and as a result, the message will not be sent.


To fix such issue, do the following:

  1. Review the failed emails:

    • Login to Billing Provider Control Panel and go to System > Logs > Outgoing E-Mail Log.

    • Find the emails with empty "To" and "From" fields with the "Error" status.

    • Delete those that are irrelevant.
  2. Install the updated rpm with a fix for this issue:

    • Log in to the Billing Application node via ssh as root and run the following commands:

      # yum clean all
      # yum update libetpan
    • Ensure that the necessary package was updated. Run the following command for this purpose:

      # yum list installed libetpan.x86_64

      which should print the following to display:

      Installed Packages
      libetpan.x86_64                1.6-2.el7.centos

      mind the version of the package: it must be 1.6-2 or greater.

    • Restart the billing service via the following command:

      # service pba restart
  3. Resend the remaining notifications manually.
