They could have had the same bug.. So it was safer to swith back to
mod_jserv..

part of the pstree (also looks like that with mod_jk ajp12.
|-libhttpd.ep---10*[libhttpd.ep]
Maby someone made a strange build of httpd, don't see the libhttpd.ep on my
machine (apache 1.3.20)

As much as possible, but since it is hosting a lot of sites, it is not
always possible.

Maby a note on the jakarta site to say that it is absolutely adviced to
switch to ajp13,because of some bugs ;-). If you have no intention to fix
the ajp12, sending the zip file is not much of use I think. If I have the
problem om ajp13, I will notify you right away ;-)
