mythweb displays broken links to preview images

[brian@…]

When I load the "Recorded Programs" page in mythweb it will typically show a few broken links for a few of the most recent preview images. Simply refreshing fills the broken links in with preview images, quite quickly -- clearly from disk.

Seems there is some kind of race or timeout issue happening.

Can you add the apache logs when this happens?

OK. It just happened again. Two episodes which are showing a broken link icon instead of a thumbnail. Looking at what was fetched for one of them:

<a class="x-pixmap" href="http://pvr/mythweb/tv/detail/3093/1365469200" title="Recording Details"
            ><img src="http://pvr/mythweb/tv/get_pixmap/pvr/3093/1365469200/100/75/-1/3093_20130409010000.mpg.100x75x-1.png" width="100" height="75"></a>

and then grepping the access_log for 1365469200:

# grep "1365469200" /var/log/apache2/access.log
1.5.2.1 - - [09/Apr/2013:18:11:54 -0400] "GET /mythweb/tv/get_pixmap/pvr/3093/1365469200/100/75/-1/3093_20130409010000.mpg.100x75x-1.png HTTP/1.1" 200 385 "http://pvr/mythweb/tv/recorded" "Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.22 (KHTML, like Gecko) Ubuntu Chromium/25.0.1364.160 Chrome/25.0.1364.160 Safari/537.22"

So the log doesn't show a 404.

And if I refresh the page, the thumbnail will actually draw the second time around.
