We have a NAM 4.0 (copper, 8 channels) on a 8x24 DR5.1. Users are complaining of receiving voicemail messages that are old. Basically, they check their mailbox at noon, no new messages, they check again at 3pm, and there are new messages from 10am.

I went through the system logs, some of the logs say:

"Enough Memory S9", when i select time, the times for these events are always 06:01 and 18:01.

any ideas
