 I am running Mythbuntu amd64 9.10 on my MBE. Myth version is 0.23.1-26231.
 I recently added a SBE running Mythbuntu 10.04 amd64. The same exact
 version of Myth is running on both. With the SBE running the MBE slows its
 responsiveness down over time. Yesterday I restarted both the MBE and SBE
 at 5PM. By 11PM I was no longer able to view any recordings. Additionally
 it takes longer and longer to navigate the View Recordings screen and to
 get the status page in Mythweb. Recordings appeared to continue normally
 during this time. At 11PM I restarted both the MBE and SBE. I was
 immediately able to view the recording that failed a few minutes earlier.
 Both BE machines were running with -v network,extra,socket. This might be
 related to ticket 7608, but this is version 0.23.1 not 0.22. The
 uncompressed log files are between 60 and 70 MB per BE (5MB to 7MB
 compressed).

 For search aiding I see these types of errors in my log:
 2010-09-15 20:00:04.059 MythSocket(1d574e0:-1): writeStringList: Error,
 socket went unconnected.

 2010-09-15 20:30:44.982 MythSocket(7f1a48449300:-1): writeStringList:
 Error, socket went unconnected.


 I don't know if it is related or important, but I am also seeing some many
 mythcommflag segfaults in the system log. The message lists either
 libmythdb or some qt library.
