While conducting a network scan of the Automate 7 server, the cpu remains mostly unnafected. However, during the scanner's third attempt at identifying the service running on port 1743 (amts), the CPU utilization spikes at 99% and remains at that percentage until the service is restarted. I've attached the packet capture of the network scan prior to the cpu spike. Thank you,

Hi Kyle,
Can you please confirm what version of AutoMate 7 you are running? Can you also confirm your OS?

Kyle,
You are posting in the AutoMate forums but mentioning server so I just want to make sure that we are looking at AutoMate and not BPA Server. Also, the task service for AM7 is am7ts.exe and not amts.exe. You mentioned amts which would apply to all versions of AutoMate except v7. AutoMate 7's default port is 7877. How are you determining that 1743 is an AM7 port? From a command line please type the following: netstat -aon | find ":1743" The results should contain a PID. Please match the PID in Task Manager to the appropriate process and let me know what you find. Also, please let me know the parameters that you are using for Nmap to cause the CPU spike as well as what you are using to determine that port 1743 references AM7.

Hi Leonard, Lastly, the nmap parameters used were: nmap -sS -sV -p 1-65535 -v -v --version-intensity 1 192.168.10.58

Hi Kyle,
Unfortunately I am not able to reproduce your issue. Do you have tasks running during the scan? If so how may tasks are running during the scan?
