I didn't try it. My application uses G1GC Should i try SerialGC?

On another enviroment my application uses SerialGC, but the problem still exists

I think that i didn't enable inferred spans `2024-02-06 21:00:51,269 [main] INFO co.elastic.apm.agent.util.JmxUtils - Found JVM-specific OperatingSystemMXBean interface: com.sun.management.OperatingSystemMXBean 2024-02-06 21:00:51,372 [main] INFO co.elastic.apm.agent.util.JmxUtils - Found JVM-specific ThreadMXBean interface: com.sun.management.ThreadMXBean...
