You are managing servers located in a corporate DMZ utilizing Cloud Enabled Management (CEM) to connect to the Notification Server. After a period of time, the Symantec Management Agent (SMA) would stop connecting which would prevent management functions such as Inventory and Patch Management. In the agent logs, you see this error:
---------------------------------------------------
Operation 'CEM: Get' failed.
Protocol: HTTPS
Host: <FQDN>:443
Path: /altiris/NS/Agent/GetPackageInfo.aspx
Connection Id: 77.4344
Communication profile Id: <Profile ID>
Throttling: 2 50 5140
Error type: Socket error
---------------------------------------------------
8.5 RU3, RU4
Throttling was set on all DMZ servers to 50% of 5MB. Agents during speed calculations would exceed 120 seconds of wait time and could not self-recover.
This issue has been addressed in ITMS 8.6.
The workaround is to either change the bandwidth throttling type to kb/s or disable throttling for DMZ systems.
