Ok so after getting wackamole to compile, I attempted to migrate my current
environment (wackamole 1.2) over to it. However I have not had any success
with wackamole picking up any of the VIPs. What am I missing, Spread looks
like it starts up fine, and all machines look like they are able to
communicate. spmonitor shows them all on the same partition. Wackamole
starts up and does not generate any errors in /var/adm/messages or on the
console from what I am seeing. Did I miss something in the new
configuration?

My env is solaris 8 on sparc (UltraSparc IIe) (3 of these) (model netra x1)
512 MB RAM

ifconfig brings up the following information.
netravis1# ifconfig -a

Well, it looks like the problem is a bus error... that's not good. I
noticed these prior to the CVS version and it was due one of the
function using an ENORMOUS stack frame.

Have you tried the CVS version? Everywhere we are running wackamole, we
are running CVS HEAD. It is quite stable.

I don't have a box here that I can replicate your problem on. If you
can debug it, please send in more information. If you compile with
debugging symbols (-g in the CFLAGS) and run it under GDB.

gdb ../sbin/wackamole
r -c /env/lvWeb/wackamole2.0.0cvs/etc/wackamole.conf -d

It should break when you hit the bus error and you should be able to run
"where" and "bt full" which will provide some good information.

Bus errors are usually caused by alignment problems (but not always) and
may be a 64bit issue.
