I seem to have a similar problem. At this very instant, I also have two
zombies of mythfrontend:

F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME CMD
0 S 1001 10143 9919 7 80 0 - 102258 poll ? 03:03:36
mythfrontend
1 Z 1001 10351 10143 0 80 0 - 0 exit ? 00:00:00
mythfrontend <defunct>
1 Z 1001 10353 10143 0 80 0 - 0 exit ? 00:00:00
mythfrontend <defunct>

I also seem to be (occasionally) having problems with mythfilldatabase
getting hung up as well as mythbackend while generating previews (whether
these are related or not, I do not know but they all started happening about
the same time):

3226 Wed Sep 23 21:12:14 2009 S ? 00:00:00 sh -c
/usr/local/bin/mythbackend --generate-preview 0x0 --chanid 2061 --starttime
20090923210000
3227 Wed Sep 23 21:12:14 2009 S ? 00:00:00
/usr/local/bin/mythbackend --generate-preview 0x0 --chanid 2061 --starttime
20090923210000

When I kill mythfilldatase and look at the output it seems to be getting
stuck updating the database:

2009-09-25 07:09:42.829 MythContext: Connecting to backend server:

====================================================================

In my particular set-up I do not use mythwelcome. I have not tried to
reproduce this problem, but it still currently exists on my BE/FE box. Here
is the information that I can share with you:

From running programs:

ken [at] mytht:~$ ps kstart_time -ef | grep myth

From the frontend log at startup:

If there is more information I can collect to help diagnose the problem, let
me know and I will try to recreate the issue. I don't plan to touch the
system unless it becomes unusable or you ask me to until this weekend.
