I've been having trouble with the MDS process running wild on my MacBook Pro 13". I've read on other support forums indicating that improperly formatted external drives can be an issue, but I have no drives connected. How can this problem be debugged and fixed?
If it helps, I do have a massive Mail archive. I have not turned off the indexing of this archive, because I haven't been able to find a correlation between the two, but I'm considering it.
(This might be normal right after doing an upgrade from 10.5 to 10.6, in which case the Spotlight search index needs to be rebuilt by
mds. But in this case it's been a few weeks.)
