I've had the same exact problem several times in the past...pinpointing
it to somewhere between post 5.1-RELEASE and 5.2-BETA as where it
started. 5.1-RELEASE and subsequent 5.1-CURRENT through mid-November
didn't seem to have this issue (for me of course). System is an IBM
Netfinity 4500R- 2x PIII SMP, ServeRAID 3L, 1G RAM. If I'm not
mistaken, the other instances of people experiencing this were also SMP
I'm not sure at what point it 'resolved itself,' but it's possible my
kernel and world were out of sync, or that I skipped doing a
mergemaster.... is now working with 5.2-CURRENT as of Jan 1....
Not sure this helps in any immediate fashion, but another data point....
