Hi I did an upgrade of two ldap server (master/slave) from 2.4.21 to 2.4.28 two days ago. And today, the master crashed, if I do an ldapsearch: root@ldap-master001 /]#---> ldapsearch -ZZ -hlocalhost -d-1 ldap_create ldap_url_parse_ext(ldap://localhost) ldap_extended_operation_s ldap_extended_operation ldap_send_initial_request ldap_new_connection 1 1 0 ldap_int_open_connection ldap_connect_to_host: TCP localhost:389 ldap_new_socket: 3 ldap_prepare_socket: 3 ldap_connect_to_host: Trying ::1 389 ldap_pvt_connect: fd: 3 tm: -1 async: 0 ldap_open_defconn: successful ldap_send_server_request ber_scanf fmt ({it) ber: ber_dump: buf=0x13c3910 ptr=0x13c3910 end=0x13c392f len=31 0000: 30 1d 02 01 01 77 18 80 16 31 2e 33 2e 36 2e 31 0....w...1.3.6.1 0010: 2e 34 2e 31 2e 31 34 36 36 2e 32 30 30 33 37 .4.1.1466.20037 ber_scanf fmt ({) ber: ber_dump: buf=0x13c3910 ptr=0x13c3915 end=0x13c392f len=26 0000: 77 18 80 16 31 2e 33 2e 36 2e 31 2e 34 2e 31 2e w...1.3.6.1.4.1. 0010: 31 34 36 36 2e 32 30 30 33 37 1466.20037 ber_flush2: 31 bytes to sd 3 0000: 30 1d 02 01 01 77 18 80 16 31 2e 33 2e 36 2e 31 0....w...1.3.6.1 0010: 2e 34 2e 31 2e 31 34 36 36 2e 32 30 30 33 37 .4.1.1466.20037 ldap_write: want=31, written=31 0000: 30 1d 02 01 01 77 18 80 16 31 2e 33 2e 36 2e 31 0....w...1.3.6.1 0010: 2e 34 2e 31 2e 31 34 36 36 2e 32 30 30 33 37 .4.1.1466.20037 ldap_result ld 0x13bb660 msgid 1 wait4msg ld 0x13bb660 msgid 1 (infinite timeout) wait4msg continue ld 0x13bb660 msgid 1 all 1 ** ld 0x13bb660 Connections: * host: localhost port: 389 (default) refcnt: 2 status: Connected last used: Thu Jan 26 21:43:50 2012 ** ld 0x13bb660 Outstanding Requests: * msgid 1, origid 1, status InProgress outstanding referrals 0, parent count 0 ld 0x13bb660 request count 1 (abandoned 0) ** ld 0x13bb660 Response Queue: Empty ld 0x13bb660 response count 0 ldap_chkResponseList ld 0x13bb660 msgid 1 all 1 ldap_chkResponseList returns ld 0x13bb660 NULL ldap_int_select It hangs at ldap_int_select (There's nothing in the slapd debug log) Same problem again after a few seconds, if I kill the daemon and start it again. (The daemon crashed, only a kill -9 helped) And now, after one hour of debug, the same problem occurred on our first slave server.... Has someone similar problems, or can somone helps me? The next thing I'll do is go back to 2.4.21, maybe that helps.... Thanks -- Raffael Sahli public@raffaelsahli.com |
