After a long round of bisecting I found that the last working version
(apart from the 1 minute delay) is 3.2.5.
I didn't find anything like this about 3.2.6 in the mailing list :-/
If I use "smbclient -L localhost" instead of "smbclient -L hp", one of
the smbd child dies silently (at least the master process complains that
it doesn't find its pid any longer) right after searching for the domain
record in ldap (with apparently a successful result).
Thinking that maybe the problem was related with ldap client libraries,
I updated ldap to 2.4.19 (only the client libraries, didn't touch the
server) but the problem persisted, so maybe that's just a red herring.
Any hint on how to debug this further?
I attached strace to the samba processes and this is what I see:
1) in the level 10 log:
[2010/05/02 17:33:38, 2, pid=2379] lib/messages_local.c:message_notify(270)
message to process 2414 failed - No such process
the last message from pid 2414 is:
[2010/05/02 17:33:38, 5, pid=2414] lib/smbldap.c:smbldap_search_ext(1200)
smbldap_search_ext: base =>
[sambaDomainName=WETRON,sambaDomainName=WETRON,dc=wetron,dc=es], filter
=>
[(&(objectClass=sambaTrustedDomainPassword)(sambaDomainName=WETRON))],
scope => [2]
2) and with strace I see that pid 2414 got a SIGPIPE writing to fd 8
[pid 2414] write(23, " smbldap_search_ext: base => [s"..., 189) = 189
[pid 2414] rt_sigaction(SIGALRM, {0x803fa895, [ALRM], SA_RESTORER,
0x40328718}, {SIG_IGN}, 8) = 0
[pid 2414] alarm(15) = 0
[pid 2414] time(NULL) = 1272814418
[pid 2414] rt_sigaction(SIGALRM, {0x803fa895, [ALRM], SA_RESTORER,
0x40328718}, {0x803fa895, [ALRM], SA_RESTORER, 0x40328718}, 8) = 0
[pid 2414] alarm(15) = 15
[pid 2414] write(8, "0\204\0\0\0\5\2\1\23B\0", 11) = -1 EPIPE (Broken pipe)
[pid 2414] --- SIGPIPE (Broken pipe) @ 0 (0) ---
Process 2414 detached
I don't see where pid 2414 opens fd 8, either strace didn't catch it or
it was inherited from the parent, but I suppose it's the connection with
the ldap server.
Bye
