Comment(by ridderman):

 I've attached another set of logs. This time I sucessfully upgraded from
 2346 to 2373, however the dirty irsync failed with a Python Memory error.
 Because Python caught it, the irsync failed gracefully and the rsync
 worked. Note that I had much more available memory this time before the
 update (~45 MB). I had used the laptop quite a bit since the last restart
 but my available memory actually increased over time. I did not open
 Browse and did not acquire an internet connection - not sure if this is
 related.

 The memory error is the same one that I've seen in the past:

   File "/usr/lib/python2.5/site-packages/bitfrost/contents/utils.py", line
 100, in mkdirobject
     entry['h'] = mkhashes(file(fullname).read())
 MemoryError

 This happens is in the "Creating contents for existing tree" step. See the
 logs for more detail. This step is also where I've seen the OOM failures.

 Now that I've upgraded to 2373, I have the new olpc-update which has a fix
 for #8190. I'll post my results the next time I get a chance to update my
 laptop.
