hi Mark,
sorry for being late to answer you, but Im currently at home with 2
broken arms, and using a PC is a pain for me.
the answer is :
jserv 1.0 shared memory is not available on *BSD in current stable
distribution.
I think this is the same for other flavours of unixes like HP UX or AIX.
I'm the culprit as I had not every OS around when I did code it.
the patch is maybe :
try to replace every instance of #ifdef _POSIX_MAPPED_FILES in the
source code (jserv_mmap.c at least)
by
#ifdef HAVE_MAPP
recompile and let us know (please send me also a private mail).
sorry for this.
