The Agent watchdog can cause a Recycle of the Agent if it detects an abnormal increase in memory usage, the Agent watchdog has logic to prevent the agent processes from leaking memory and using up too much system resources. However, newer OS and newer builds of code tend to use larger amounts of memory as a baseline.
This might also happen when there are many targets being monitored, the default values might not be sufficient, leading the watchdog to assume that the Agent is consuming too many resources and hence recycles it.
There are no abnormal terminations or hangs detected so no core dump files get generated.
Content of the <AGENT_HOME>/sysman/log/emagent.nohup has the following entries:
