Hi,

        I am running openldap-2.1.21 with BerkeleyDB 4.1.25 and OpenSSL
0.9.7b. I use bdb backend.
        When I use perl-ldap-0.2701 to modify entry in the LDAP server,
the operation stop suddenly and the following is the log of the slapd.

        The bdb backend contains 90000 entries and I already set
"sockbuf_max_incoming 1000131072" in slapd.conf. Is the problem caused by
slapd configration or the BerkeleyDB ?
        I look forward to see your reply. Thank you.
