Answer 1

Well, just for laughs, I rebuilt the indexes of the wiki server and it looks like it fixed these memory errors.
The following terminal commands stop the wiki server, rename three index files and restarts the wiki server. The index files are rebuilt (can take a while) when the wiki server is restarted.
+sudo serveradmin stop teams+
+sudo mv /Library/Collaboration/globalIndex.db /Library/Collaboration/globalIndex.db.old+
+sudo mv /Library/Application\ Support/Apple/WikiServer/directoryIndex.db /Library/Application\ Support/Apple/WikiServer/directoryIndex.db.old+
+sudo mv /Library/Application\ Support/Apple/WikiServer/sessions.db /Library/Application\ Support/Apple/WikiServer/sessions.db.old+
+sudo serveradmin start teams+
If anyone knows what other files should be renamed/deleted for a really comprehensive rebuild, I would be interested. Unrelated to the memory error (I assume) there are users in the redundant and unsynchronized wiki user directory that were long ago deleted from Open Directory.
