<p class=MsoNormal>Afternoon Guys,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve got what I would consider to be a strange memory
leak within an application I’ve been working on. When the application is
running the consumed system memory creeps up slowly, getting higher and higher.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>However, when looking at ‘top’ to display the
memory allocation for all the applications, the actual assigned memory to the ‘python’
process doesn’t appear to change, it consistently looks like:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>2414 root 20
0 9516 6316 3148 S 0.0 2.5 0:03.62 python<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>However the currently used memory for the entire system,
shown here:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Mem: 256760k total,
35588k used, 221172k free, 2096k buffers<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Continues to escalate until the system runs out of memory. I
can be pretty sure that this is something to do with my application as whenever
the app isn’t running then the memory usage doesn’t increase.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>An additional strangeness to this is that when my
application is killed, the memory doesn’t drop back down again? Is that
normal? My understanding of a memory leak was that when the application dies
the memory will be freed back up again.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Can any offer any suggestions as to what is causing this
problem? Is it perhaps not my actual application but something I’m
calling from within it?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Cheers,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
