Shulou(Shulou.com)06/01 Report--

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:
