don't have time right now, but if you have looked at the AV posibility as Jim suggested and still no go, in looking at one of the files I noticed 2 things
-
[b]Sharing Plugins: VSocketReader::Bind: Socket bind failed: 10048 [/b]
this could mean that two processes are trying to use the same socket or there is an issue with port access (maybe port 80?)
If you are on a network could you turn off media server and try running your main PC locally to see if it crashes.
Also this podcast is looping
"http://straightdope.infoble.com/rss.xml" maybe you could try editing or removing some of the podcasts temporarily (although I sort of doubt this would cause a crash)
I think you should reset (clear the log) - I can't tell which file is the last before the crash. It shouldn't be that big unless it is running for a long time. If needed just post the end of it or put it in dropbox or googledrive maybe?
