I though I had it. I ran 1.8e on our AIX system all day Saturday and it worked fine. I put 1.8d back for the rest of the weekend and started 1.8e this morning, figuring that I finally got there. Well rats! So I figured I'd have to back up *again* to 1.8d. As I was typing this note, I recalled seeing something in the release notes about large sites. We have over 3,900 lists. I pulled out the notes and found the section about "Enhancements for the HPO version" and set "TUNE_MANY_LISTS=1" and restarted, holding my breath. Whew! That seems to have solved the problem. Yay! Was this variable around last September when tried 1.8e? -- What do fish say when they hit a concrete wall? . . . Dam!
