<p>Prometheus deployed on kubernetes using prometheus operator is eating too much memory and it is at present at ~12G. I see <code>/prometheus/wal</code> directory is at ~12G. I have removed all <code>*.tmp</code> files but that couldn't help. 
Unable to figure out the solution for this problem. Any suggestions ??</p>

<p>Reduce your retention time or reduce your number of time series.</p>
