I assume this is due to some workflow failing, however, there doesn't seem to be any indication as to which.
Is it possible to log at least the id of a workflow when a specific workflow fails for any reason?
SugarCRM edition 8.0 Professional.
Found the reason. Some workflow was trying to send emails with invalid outbound email configurations. Added a try catch block into SmtpMailer.php to redirect failing mails to be sent from another, valid address instead. I also redirected the recipient to myself. This allowed me to detect which workflow failed and deleted it.
