<pre wrap="">Hi,
I've seen a few threads on backend crash problems, so I thought I'd add
my info to the heap. I have not been able to diagnose this problem for
some months now, despite quite a bit of hunting through this list. I
have set up a cron job to periodically check for the dead backend and
restart it within a few minutes. When this happens the restart script
appends a message "BACKEND DEAD - RESTARTING" to the mythbackend.log so
I know that it has corrected a dead backend situation. Any ideas/clues
how to test this problem further are greatly appreciated. It is
probably my #2 biggest myth problem at the moment, and would love to
figure it out.

Are you sure all MythTV machines/clients on the network are using the
same version of the software?

Pretty sure - I will double check. When these machines were originally
setup over a year ago, I took care then to keep the same version.
Always possible I could have updated somewhere along the line without
thinking clearly. I'll double check them all.<br>

<pre wrap="">Are you using the internal MythTV file streaming for access to remote
files, or are you storing your recordings (mythbackends) and accessing
them (mythfrontends) over NFS or similar (which it looks like with
your /mnt/store recording dir?

Both, really. Much of the time I see problems streaming live TV and
recordings, but that's because it probably accounts for most of the
viewing that is done ;-) I also have a lot of video accessed from
several locations via Samba-mounted dirs. I haven't really nailed down
whether one case or the other is correlating more/less with the
problem, since unfortunately I am usually not present for the events
(the rest of the family gives me a gripe hours later about it ;-) <br>

As your crashes all seem to be relating to file transfers between
hosts, I would start investigating here.
