Error MScheduler - Email

[osy gomez]

Good Morning, An error is being generated when configuring the sending of email through the agenda. In receipt configured users and one of them forwards mail to multiple users from a mail server. IDempiere users correctly observe the msg but the user who forwards from the mail server has two messages, one correct and the other with this error: MScheduler [1000001-MyTestReportJasperS] - ProcessError java.sql.SQLException: You can't operate on a closed Connection !!! Logs deleted = 0

Any idea of ​​that error?, thanks in advance
