OMC cloud agent often stops after installation
Use the customer's test account to do an OMC cloud agent test, the agent is also installed, and the logs are automatically collected.
The next day, I found that agent was out of service, so I started it, the state was normal, and I found it stopped again in the afternoon.
There seems to be a problem:

At first glance, the java virtual machine does not have enough memory. Take a look at metalink and find the same problem:

At present, the state is normal, look at it tomorrow, if it is still running, the problem will be solved!
