copied!<p><strong>Short answer:</strong> You're probably running out of memory.</p> <p><strong>Long answer:</strong> (This is highly speculative, using lots of guess work) </p> <p><code>PMEM</code> <em>is a module in android that handles allocating large chunks of contiguous physical memory</em>. <br> Apparently it's also relevant to graphics, see <ul> <li><a href="http://www.slideshare.net/jserv/design-and-concepts-of-android-graphics" rel="nofollow">http://www.slideshare.net/jserv/design-and-concepts-of-android-graphics</a></li> <li><a href="http://www.slideshare.net/jserv/accel2drendering" rel="nofollow">http://www.slideshare.net/jserv/accel2drendering</a></li> </ul> <br>This presentation is the best thing I could find, and it's sadly lacking in explanations. <br> However, it does mention that various graphics related things in android use large buffers allocated via PMEM.</p> <p>PMEM apparently creates a memory structure with several buffers inside one contiguous bloc*.<br> <code>base</code> is the (physical? mmaped virtual? I'm not sure) <em>base address of the entire PMEM buffer</em>. <br> <code>Size</code> seems to refer to the <em>size of the indivial "sub block"</em>. <br> <code>offset</code> gives the <em>start address of the specific "sub block"</em> <br> <code>fd</code>, or file descriptor, is used to <em>access</em> that specific buffer <br></p> <p>Since you mention that values of <code>fd</code> above 86 lead to bad things, and the above example has fd = 76, I'm guessing you're simply running out of memory <br> (PMEM can only handle 12 buffers, so maybe you're running into that limit, too?)</p>
