Ok so this means that port 163 was failed to be bound to. This may have happened because another process has already bound to it. If on Windows, I would check to see if Windows SNMP is running as it uses the same port and interferes with us. Or possibly another outside process has it opened.
Another thing that could have happened is that an alert was opened and sent out via SNMP (could be caution or danger). Every SNMP alert that gets opened has to get closed. When that alert closes (goes below caution or danger depending on how the alert is set up), another SNMP is sent closing it.
So its possible that the SNMP open trap went through but never closed. Thus any subsequent open traps will fail with the bind failure message.
You could search the logs for this, but probably best to open a case for investigation.
