Created attachment 8938 [details] Logfile - debuglevel 3 I upgraded Ubuntu 8.04 to 12.04 (via 10.04) and also the included samba version changed from 3.0.28 to 3.6.3. Since then we have got the problem that from time to time windows xp computers get the error message "Delay Write Failed" and some programs crash (e.g. firefox - profiles stored at network drive). We already added "keepalive" and "deadtime" to our smb.conf and tried different values, but the problem still resists. This is our smb.conf file: [global] workgroup = NT server string = filer01 security = user encrypt passwords = true server signing = disabled lanman auth = yes unix extensions = no socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 keepalive = 45000 deadtime = 15 smb ports = 445 local master = Yes interfaces = bond0 wins support = yes domain logons = Yes domain master = Yes preferred master = yes time server = yes unix charset = UTF8 load printers = yes printing = cups printcap name = cups disable spoolss = yes username map = /etc/samba/smbusers logon script = login.cmd logon path = logon home = logon drive = L: log file = /var/log/samba/log.%m max log size = 5000 os level = 33 passwd program = /usr/sbin/smbldap-passwd %u passwd chat = *password* %n\n *password* %n\n *changed* add machine script = /usr/sbin/smbldap-useradd -w "%u" add user script = /usr/sbin/smbldap-useradd -m "%u" ldap delete dn = Yes add group script = /usr/sbin/smbldap-groupadd -p "%g" delete group script = /usr/sbin/smbldap-groupdel "%g" add user to group script = /usr/sbin/smbldap-groupmod -m "%u" "%g" delete user from group script = /usr/sbin/smbldap-groupmod -x "%u" "%g" set primary group script = /usr/sbin/smbldap-usermod -g "%g" "%u" passdb backend = ldapsam:ldap://127.0.0.1/ ldap admin dn = "cn=admin,dc=thisnet,dc=here" ldap ssl = off ldap group suffix = ou=Groups ldap user suffix = ou=Users ldap machine suffix = ou=Computers ldap suffix = dc=thisnet,dc=here ldap delete dn = no use sendfile = Yes debuglevel = 3 debug class = yes [homes] comment = Home Directories valid users = %S browseable = No read only = No inherit acls = Yes create mode = 0700 [programm] comment = Programme path = /srv/samba/programm read only = no browseable = yes public = no create mode = 770 directory mode = 770 force group = alle And attached the logfile from a windows xp computer at the time the "Delayed Write Failed" failure happend. Any tips, suggestions? Before the update we had no problems! No hardware changes. Thx Manfred
3.6.3 is not a version you should use, it is old, 3.6 has seen *many* fixes since. Please update at least to the latest 3.6 or the lastest 4.0 version. You can find ready built packages for ubuntu also. If the error still happens, please attach a level 10 log of the client's smbd process, see https://wiki.samba.org/index.php/Client_specific_Log . I'll close this as worksforme. Please reopen if you tested with latest versions and still get the error.
