Another slapd lockup (ITS#31)

Hi!
This is an other slapd deadlock problem. I'm still using my test
database (->ITS#24).
Execute the following command:
ldapdelete -D "cn=normalUser, O=YOUR ORGANIZATION NAME, C=US" -w 123
cn=normalUser, O=YOUR ORGANIZATION NAME, C=US
ldap_delete: Insufficient access
Ok, everything seems fine. But have a look at "top":
PID USER PRI NI SIZE RSS SHARE STAT LIB %CPU %MEM TIME COMMAND
566 root 0 0 968 892 516 R 0 84.2 1.4 1:19 slapd
Pid 566 is the tread that handled my connection. slapd still accepts new
connections, but pid 566 has crashed.
Perhaps gdb can provide you with additional informations:

Btw: On Linux/sparc SLAPD crashes completely.
Happy new year,
