We have Avaya IP Office 5.0(8) with Delta Server V5, every day at 5:40am a mail is received with message ¨The Delta Server is Down¨, 3 minutes after another message comes ¨The Delta Server is now Operational¨ this messages are from Delta Server IP address and happens every day. Is this a normal behavior or there is something going on here?? Any help will be appreciated.
