[mythtv] backend dying while mythweb is creating previews for recorded programs

Hi,

Has the code for static preview generation changed since .16
 to make it happen in the background?

I see '(0 retries remaining)' in the logs for remote filetransfers
How can I change that, so that it tries again?


Here's what's happening:

i start by clearing out the png files
#rm -f /mnt/store/*.png /var/www/html/mythweb/image_cache/*.png

then i go to the recorded_programs.php page in firefox and 
when the backend is busy with commflagging or recording, 
only a few preview images are shown

sometimes the backend seems to crash, 
but upon further investigation it doesn't really segfault 
but just exits gracefully right after a 
2005-02-22 00:00:16.986 Unknown file transfer socket: 18
or similar, in the log

other times it gets stuck with tons of 
"waiting for a thread" messages
see preview-2.log
i <ctrl-c>-ed the backend and got preview-4.bt

most of the time the files are actually created in /mnt/store
but they just don't get copied over to image_cache
so hitting reload copies them over

i have toyed with the idea of adding a timeout to let the file creation 
complete before trying to copy the png over but no luck so far

i have added some debug statements to see what's going on
preview-4.diff produces preview-4.html.txt
and
preview-7.diff produces preview-7.html.txt 
(with the backend running inside a while loop)

i am stumped
:(
