What happened?

We started with this latest version of the plugin, seems like this caused CPU spike over time.
Please see the screenshot below, this caused increased latencies in the server causing application timeouts eventually and we had setup a restart cron every 30 minutes as a workaround. So, if you see the graph it rapidly increases and after 30 min it drops down. We tried different plugins and finally found this opentelemetry plugin as the savior here. After switching apm to opentelemetry, the cpu usage stabilised. Please look into this. Below graph shows CPU usage with ddtrace and opentelemetry plugins.
