When the path of a service points to a directory mounted via NFS the following error occurs at disconnect: [2016/02/01 04:20:37.135774, 0, pid=14590] ../source3/smbd/smbXsrv_tcon.c:974(smbXsrv_tcon_disconne ct) smbXsrv_tcon_disconnect(0x1d2dc409, 'someuser'): set_current_service() failed: NT_STATUS_INTERNAL_ERROR followed by a core dump. Reason is failing to chdir to the path due to root_squash on NFS. This does not happen every time. It depends on the state of the process. One sure way to produce this error is to immediatly disconnect after connect (something like smbclient -c 'exit').
Can you get a stack backtrace and post here for the coredump please. Even though this is an error condition we shouldn't core.

Ok, this isn't the trace I needed, but thank for trying. To get the trace, add the line: panic action = /bin/sleep 999999 into the [global] section of your smb.conf. Reproduce the problem. Use ps to look for the sleep process, then find the pid of its parent. Then type: gdb -p <pid-of-crashed-process> /usr/sbin/smbd Then type "bt" to get the backtrace. Ensure you have symbols loaded. Thanks !

Hi everybody, I can confirm this issue. Two machines with RHEL 7.2 and Samba Version 4.2.10 has the same problem. If the chdir to a folder is failing because of an permission denied error (User tries to access with root, but NFS is exported with root_squash); smbd throw an NT_STATUS_INTERNAL_ERROR then NT_STATUS_IO_TIMEOUT and do an core dump.

I have observed the same problem on both Solaris 11.3 and RHEL7.3 Samba servers (4.4.14) with NFS backed shares that have root_squash with same stacks as below. On a busy samba server (100's of users) where all data comes from NFS and all shares have root_squash there was crashes every few minutes. What makes it worse on Solaris is that Samba running under SMF (the default way to run it) will restart all smbd processes if parent or child process exit with a core dump. On other systems like RHEL7.3 it is not so obvious this is happening, particularly if the smbd process was about to exit anyways, because it doesn't impact other smbd processes. If you make these changes on Solaris 11.3 it will change SMF so that other smbd processes do not restart if one process core dumps. $ sudo svccfg -s svc:/network/samba:default svccfg> addpg startd framework svccfg> setprop startd/ignore_error = astring:"core" svccfg> exit $ sudo svcadm refresh svc:/network/samba:default $ sudo svcadm restart svc:/network/samba:default After making above change we went from lots of user complaints (crashes in middle of copies/saves etc) to zero complaints.
I believe we are experiencing the same bug serving samba v4.8.3 from Centos v7.6.1810. We have NFS mounts to the samba server using root_squash. Our clients are Windows Server 2016. At apparently random times, child processes of the samba service appear to crash and sometimes trigger a cleanup. I can tell when it happens as a cascade of (partial auth) events take place while watching smbstatus -p. Example: Samba version 4.8.3 PID Username Group Machine Protocol Version Encryption Signing ---------------------------------------------------------------------------------------------------------------------------------------- 10741 (auth in progress) redacted (ipv4:redacted) SMB3_11 10752 (auth in progress) redacted (ipv4:redacted) SMB3_11 10769 (auth in progress) redacted (ipv4:redacted) SMB3_11 10771 (auth in progress) redacted (ipv4:redacted) SMB3_11 10781 (auth in progress) redacted (ipv4:redacted) SMB3_11 During this time, the Windows Servers become fully unresponsive, until either samba triggers a cleanup or I manually restart the service. All users are affected during the event. They basically can't work and it sometimes kills active batch jobs utilizing the share. I was finally able to capture the relevant log trace for 2 such events, provided below. In these 2 cases, things seem to recover quickly on there own. In others, it lasts minutes and I'll often restart smbd to force a 'cleanup'. Any help is much appreciated, we've been banging our heads on this issue for quite some time.
