Ok, now I got the point, also Richard had the same problem. Assume we have 10 threads, and thus ticket numbers 1-10. Now we get a reply to #2, which then pops up to the top of the list. A new message increments the top entry of all entries, and then wrongly gives a new #3, instead of #11.

I fixed this in SVN revision 2073, where elogd searches all logbook entries for the largest index, then increments this one by one. The fix will be contained in the next release.
