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.

Comment (by brian@…):

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"
1.5.2.1 - - [09/Apr/2013:18:11:59 -0400] "GET
/mythweb/tv/get_pixmap/pvr/3129/1365469200/100/75/-1/3129_20130409010000.mpg.100x75x-1.png
HTTP/1.1" 200 384 "http://pvr/mythweb/tv/recorded" "Mozilla/5.0 (X11;

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.

Comment (by brian@…):

Replying to [comment:4 kormoc]:
> I can't reproduce this.

But I can with 100% reliability so it seems a bit short-sighted to close
the ticket just because one person cannot reproduce the problem. Perhaps
these are related since they occur when trying to load the Recorded page:

}}}

But as I have mentioned, they are transient/load related since they only
occur on the first attempt to load the Recorded page and the broken links
will go away if I refresh the page which of course instructs the server to
regenerate the previews.
