Well, the development of elogd with it's message numbers was actually stimulated by
the problem you mentioned. After that all those problems went away. Another
incarnation of that problem is if you edit an mhttpd log file manually. Afterwards
the file offsets are different and the system gets corrupted. To fix this properly,
one would have to backport the el_xxx functions from elogd to mhttpd, or, even
simpler, remove the elog functionality in mhttpd and "force" everybody to use elogd
(after doing elconv to convert the files into the new format).
