</span>From a quick search it looks like the stuff I remember was early June 2014, around 27.2.<br>
<br>
The bigger leaks were in Master but there were a couple of small leaks in 0.27 as well.<br>

There has been some detailed talk on this list previously about memory usage. One comment I recall was that often systems will cache heavily if there is memory because, well, why not - unused memory is wasted memory. I don't know if this is what your seeing? Maybe others will comment? How are you measuring memory usage?</div></div><br>_______________________________________________<br>

</blockquote></div><br></div><div class="gmail_extra">So I have tested three mythtv systems: 1-gentoo and 2-arch<div>All exhibit the same result of increased memory use while switching between tv recordings. Mark Perkins has suggested that this memory use behavior is normal. If that is the case then I have no problem, only a better understanding of how mythtv works now. </div></div></div>
