Replica core dumps if unable to contact it's Master after 2 hours.
Replica is set to refresh and persist.

To reproduce...

Shut down slapd on Master server and/or, if multihomed server, shutdown the
replication interface.

After 2 hours (the os keep_alive_interval) the log will report:
Feb 28 12:30:15 dpdsrass1 slapd[25552]: [ID 539778 local4.debug] do_syncrep2:
rid=123 (-1) Can't contact LDAP server
Feb 28 12:30:15 dpdsrass1 slapd[25552]: [ID 664938 local4.debug] do_syncrepl:
rid=123 rc -1 retrying

And ldap will coredump shortly there after.

The log entry mentionned above do appear in the log (every 2 hours) if there is
no traffic from the Master to the Slave and the Master can be contacted, so no
coredump.
