Question:

I am getting Alarms from my robots "Unable to spool Message" What does this mean and how do I correct this?


Answer:

Generally speaking when we see the message "Unable to spool message"
There are one of three reasons
1) we can not write out to the local file system or the disk is full.
2) There is something blocking the port we are trying to communicate on such as a firewall. Firewalls should be disabled or allow port 48000-48050.
( you would also need to set first_probe_port = 48000 in the robot.cfg)
3) the robot is temporarily busy. 

For this case, excluding the Nimsoft folder from your antivirus software resolved the case.
