The free disk space is low on SSB.
When the limit of disk usage is reached SSB stops collecting the logs.
See Basic Settings | Management | Disk space fill up prevention (dsfup)
Then archiving processes moves the data from the SSB to the archive share.
That way there is sufficient disk space to start collecting logs again.
An e-mail alert may be sent out by SSB with the following subject and content.
(See Basic Settings | Alerting & Monitoring | Health related traps | Disk usage is above the defined ratio)
1. Check if the services are still stopped by disk space fill up prevention (dsfup)
The following status message can be seen at "System monitor". See the screenshot below.
Disk fill-up prevention active! Rejecting connections!
If that is the case, continue from step 3.
2. Check if dsfup has stopped the services
Disk usage ratio limit reached, stopping services
Disk usage ratio went below limit, restarting services
(a) Move you mouse over the graph bar of "Disk" at the System monitor frame
(b) Basic Settings | Management | Disk space fill up prevention
3. Reduce the retention days in the archive policies to keep less data on the box.
4. Run archiving
If the outage of log reception was not caused by the disk space fill up prevention, open a support ticket with a fresh debug bundle attached.
