<div dir="ltr">Hi , <div><br></div><div>Thanks for suggesting the changes. </div><div>we have applied the relevant changes to config file for statistics and RAM upgrade. Things seem to be stable now but we will monitor the usage to see if it jumps off again.<div>
here is a screenshot of how its looking now. Please let me know if this is promising , also is there any possibility of memory leaks and how we can avoid them?</div><div><br></div><div><br></div><div><img src="cid:ii_14814cc23d5db5c0" alt="Inline image 1" width="562" height="186"><br>

<br>
</div>Yes, message rate stats depend on fine grained statistics. This is mentioned<br>
in the docs.<br>
<div class=""><br>
> Also we are bumping up from the RAM from 16G to 32G<br>
<br>
</div>You can also bump the watermark ratio depending on what other software<br>
may be running on the same machine/VM.<br>
(but remember that OS and system services<br>
also need RAM, as do file system caches, so going above 0.85 is probably<br>
not a good idea)<br>
