One thing I've done in the past was to use C-M-! and run a grep command
which will give me the lines I want (and not too much cruft). Then you
get a temporary buffer, with which you can't accidentally blat your log
file by saving (so you needn't be scared of deleting lots more stuff) and
which is hopefully small enough the Emacs won't get upset about buffer
size.
If it's a regular job, I suspect one could write a short elisp function
to get the relevant bits in this way, and maybe rename the buffer to
something more informative than the standard thing with ** in it.
