Thank you for sharing your configuration. It has been redacted quite a <br>
bit so I'm not 100% sure I'm not missing something, but I don't see <br>
anything that would explain your issue. Would you mind sharing the <br>
output of "dumpStats()" executed via the console? I see you are sending <br>
metrics to a carbon server, is there anything unexpected showing up in <br>
your graphs? Sudden spikes of queries, high CPU usage, CPU usage spikes, <br>
etc?<br>
<br>
Best regards,<br>
<br>
