In the last few days you might have noticed a very large increase in network and CPU usage of your manager.
The local tomcat management page shows a very high number for "Bytes sent ".
Example from https://localhost:8081/manager/status in the Data Center Security (DCS)
In the section "http-bio-443" look at the 2 lines below :
Max threads: 200 Current thread count: 50 Current thread busy: 0
Max processing time: 167655 ms Processing time: 830.91 s Request count: 19463 Error count: 1364 Bytes received: 33.79 MB Bytes sent: 778673.23 MB
The Bytes sent by the manager is very high.
In some agents you might notice that the agent.out file becomes very large.
For example in the default install path:
Directory of C:\Program Files (x86)\Symantec\Data Center Security Server\Agent\sdcsslog
30/04/2018 05:28 <DIR> .
30/04/2018 05:28 <DIR> ..
05/05/2018 07:22 1,347,105,051 agent.out
These agents have been set to trace logging level.
This affects all version of DCS.
Symantec has released an agent fix that resolves the issue. There are 3 versions of the agent installer depending on the version that you are using:
