Description Nick Semenkovich 2013-05-08 17:53:54 UTC 
Built from:

commit bf332392e15e4a2b8799101e3ddae194dca36d13
Author: Jeremy Allison <jra@samba.org>
Date:   Fri May 3 10:06:39 2013 -0700

    Fix warnings and one compile error caused by newer gcc 4.7.


Right at the crash time, log.smbd filled with a lot of errors like:

In log.smbd, I now see a lot of:

Any thoughts/advice?
Comment 3 Jeremy Allison 2013-05-08 18:33:50 UTC 
Looks like a problem when tearing down a client connection after the client has dropped the connection.

Just noticed that the user (becky) who's listed in the error:
[2013/05/08 12:08:16.832221,  0] ../source3/smbd/close.c:1064(close_directory)
  close_directory: Could not get share mode lock for
becky/AppData/Roaming/Microsoft/Internet Explorer/Quick Launch/User Pinned

... is using machine AIO6, which is the only machine that has this intermittent error in log.samba (I opened bug #9848 for this message):

[2013/05/08 13:15:49,  0] ../source4/rpc_server/drsuapi/writespn.c:237(dcesrv_drsuapi_DsWriteAccountSpn)
  Failed to modify SPNs on CN=AIO6,CN=Computers,DC=corp,DC=aldinetravel,DC=com: error in module acl: insufficient access rights (50)

Not sure if these are related.


(I'm generally confused/slightly concerned by the number of "Oplock break failed for file ... replying anyway" messages. Users are only logged into single machines, rarely roam, and don't access files concurrently. All are on hardwired desktops, and the switch RMON stats shows no errors.)
Comment 5 Nick Semenkovich 2013-07-31 20:23:43 UTC 
Haven't seen this in a while. Likely fixed/invalid.
Comment 6 John Mulligan 2014-01-30 21:15:38 UTC 
I began hitting this recently on Samba 4.1.3 and 4.1.4 and found an easy way to reproduce it on my system(s).

Client: Windows 8 (Enterprise, x64)
Server: Samba 4.1.3-2.fc20 on Fedora 20  -and- Custom compiled 4.1.4 rpm on same server
Both are virtualized. Self compiled Samba source is from the official 4.1.4 tarball.

I mapped a share to the windows client as drive J:
Start the following job: xcopy /S /I /Y /C c:\Windows j:\xc3
On the server I run a short python script that restarts smbd after sleeping a random interval between 5 and 30 seconds. 


Samba cores in the following manner after every 5th or 6th restart, frequency varies though.  Additional attachments to follow.

FWIW, I haven't seen this in a long time. Closing for now.
Comment 10 Michael Zeis 2015-02-25 17:14:06 UTC 
I am hitting this same crash with 4.1.16, so the problem appears to still be there. Similar to what was mentioned in comment #6, the problem started showing up while restarting smbd multiple times with active connections doing file copies within the share.

In my case the clients are connecting from Macs, not Windows.  The authentication is being done using LDAP/Kerberos.   Here are the related smb.conf settings:

    security        = user
    password server = *
    passdb backend = tdbsam
    kerberos method = dedicated keytab
    dedicated keytab file = /etc/krb5.keytab


Here is the stack trace from the log:

I am only replying to this because it is still open and because it was the first hit when I entered my errors into Google...

I had these same errors on Samba 4.5.10.  It took me a bit to notice that the real clue was in a different log file.  The real problem was that my tmpfs /run mount was full.  Samba's lock file database file was broken because there was no room to make changes.
