In our case we set olcDbQuarantine to: 10,30;60,+ and when we got a temporary network timeout from all back-end ldap server this is what we saw in the slapd logs. Oct 7 21:30:58 proxy slapd[330]: conn=632725 op=0 ldap_back_retry: retrying URI="ldap://back01 ldap://back02" DN="" Oct 7 21:30:58 proxy slapd[330]: conn=632725 op=0: ldap_back_quarantine enter. Oct 7 21:31:08 proxy slapd[330]: conn=632759 op=0: ldap_back_getconn quarantine retry block #0 try #0. After that the only method to recover was either to restart the whole process or reset the value of olcDbQuarantine. Thanks, Nikos
