About 20 minutes after the back-ldap "retry" situation described in my post to
openldap-software (sorry for no link but it's not in the archive yet), slapd
started gunning the CPU with yield()s. See
https://www.nbcs.rutgers.edu/~richton/richton-20060216-trace.txt for backtrace
from gcore(1) when it was gunning CPU. I also have an image from using gcore at
16:11 (while I was waiting for the retry to take place, when service was
degraded) and from after I sent a kill -INT (which was insufficient; I had to
kill -9 the process).
