I've been seeing that as well, although I think it's unrelated (mythweb 
is a separate php application)...

I'm testing the following patch on my system which seems to improve it:

--- modules/tv/get_show_details.php.distrib    2014-10-04

  <?php
  // Attempt to force some caching, will make secondary views so much 
faster.
-    header('Cache-Control: max-age-'.($_REQUEST['starttime'] - time() + 
604800));
+    header('Cache-Control: max-age=7200, public');
      header('Pragma: ');
-    header('Expires: '.date('D, d M Y H:i:s e', $_REQUEST['starttime'] 
+ 604800));
+    header('Expires: '.date('D, d M Y H:i:s e', time() + 7200));
      header('Content-Type: application/json');

      $program = load_one_program($_REQUEST['starttime'], 
$_REQUEST['chanid'], false);

This changes the cache headers for the ajax requests to be fixed at 2 
hours (7200 seconds).  Previously, they were set to the program 
starttime + 10 days, which is fine if your guide data never changes once 
it's been inserted, however often that's not the case...

Actually, given that's been running successfully for me for a while now, 
I'll look to submit this patch.

thanks,
Alex
