Forum OpenACS Q&A: Re: freebsd 5 -current, aolserver 3.4.2, pg 7.2.4, openacs 4.6.3 anyone?

I found the problem, at least partially.  It seems to be a threading issue.  Are you using libthr?  I set up /etc/libmap.conf to use libthr instead of libc_r.  After I changed to using libc_r, nsd starts up fine in the background.  I haven't yet tried it with libkse, but I'll probably do that later today.
Okay, I just did it.  I set up /etc/libmap.conf like so:
libc_r.so    libkse.so
libc_r.so.5    libkse.so.1

It works fine so far.  Looks like libthr isn't the one to use with aolserver, for now.
