Myself and other OpenLDAP developers routinely develop and test on amd64,
and I don't experience anything like that.  I'm using Linux with 2.6
kernel, so it might be some OS related issue.  Can you attach the process
with gdb when it's in that state and produce a backtrace of all threads?

$ gdb
(gdb) thread apply all bt
