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:
192.168.1.12:6543 (try 1 of 1)

------------This is where I killed it at 13:40, 25 September.
