I'm having an issue with the report scheduler on Jasperserver, is a strange behavior specifically with the email functionality, i have configured a Job to create and send a very simple report, the file is being created all the times but the email notifications sometimes is being send and some other not, there is no configuration changes on the job, same destination address, same time, same file etc, does anyone had experienced this issue before? any idea why this can be happening?
On the jasperserver UI, hover on View and select messages. This would give you the error, share the error on this page.
Also configure the scheduler to send you a mail in case of a failure and that can be done by editing the scheduler, clicking on the notification tab and filling the details under "Send job status notifications". Also check the two select boxes named as Include report job information and Include stack trace.
