1)
Antivirus scanning of UIM components
https://ca-broadcom.wolkenservicedesk.com/external/article?articleId=1371522)
The default port range starts at 49152 and goes to 65535 or 16K ports. This can be changed by a Windows configuration option to start at port 1025, thereby allowing 64510 ports before exhaustion.
There are 2 recommended changes to help resolve this problem:
a. Change the ephemeral port range:
netsh int ipv4 set dynamicport tcp start=1025 num=64510
netsh int ipv4 set dynamicport udp start=1025 num=64510
netsh int ipv6 set dynamicport tcp start=1025 num=64510
netsh int ipv6 set dynamicport udp start=1025 num=64510
b. Change TcpTimedWaitDelay to 30 seconds in the registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters
Might need to reboot the server after changes
Please check with your windows admin for additional info on this point since this is related to OS settings

Can try
1)
Upgrade to below from UIM hotfix index if running lower versions on Primary
hub_7.97HF6
robot_update 7.97HF9
2) Ensure Nimsoft folder excluded from AV scanning
3)If OS is Win 2012R2 check the dynamic port range for outbound communications is increased
netsh int ipv4 show dynamicportrange tcp

This is not enough information to help.
Set your loglevel to 3 and log size to 35000 in the hub.cfg and restart to get more information.
If you are running hub and controller 9.20 update to the latest hotfix on the hotfix site that might help.
For the community to help more we will need more information such as os type and version as well as probe versions and any recent changes.
