I was able to get a core dump of slapd.  It says I'm missing one module (libtool-ltdl) but here is what gets reported.

Core was generated by `/usr/sbin/slapd -h  ldap:/// ldapi:/// -u ldap'.

Program terminated with signal 11, Segmentation fault.

#0  ldap_chain_op (op=<value optimized out>, rs=0x7f318d51ca00, op_f=0x7f319d7521e0 <ldap_back_search>, ref=0x0, depth=0)

    at ../../../../servers/slapd/back-ldap/chain.c:418

418 for ( ; !BER_BVISNULL( ref ); ref++ ) {



It seems all was fine up until about a week ago.  Then my replicas started dropping off 1-3 times a day.


Ideas?
