Thanks Simon. Yes, it was the new DB format that was my problem. I was
updating my Gentoo box and part of that update (about 30 differant
packages in total) included an upgrade from 2.1.x to 2.2.x. My bad for
not checking the relnotes prior to letting the update run.
I reverted back to 2.1.5 to get me running again, then did my homework,
re-ran the update to 2.2.8, converted my database to skiplist format and
now all is well.
Thanks,
Mark
