Hi,
I'm hoping somebody can point me in the right direction. My samba version
is samba-4.2.10-6.2.el7_2.x86_64. I have lots of daily core dumps (~20 on
each machine daily) and I have no clear idea why. I'm including the stack
trace below. It looks like the problem is related to "invalid
lock_order".
Any ideas?
Thanks,
Sergei

Hi Rowland, Thanks for taking the time to look at this. I will post the log 10 output a bit later. Btw, what logs with log level 10 are you interested in? Here’s my samba config with sensitive info replaced with placeholders: [global] access based share enum = yes browseable = yes comment = <COMMENT> create mask = 0660 directory mask = 2770 force group = fts_data path = <PATH> guest ok = no public = no writeable = yes valid users = +GROUP1 +GROUP2 vfs objects = full_audit acl_tdb full_audit:prefix = %u|%I|%m|%S full_audit:success = mkdir rename unlink rmdir pwrite full_audit:failure = none full_audit:facility = local7 full_audit:priority = NOTICE # Example share [SHARE_NAME] access based share enum = yes browseable = yes comment = <COMMENT> create mask = 0660 directory mask = 2770 force group = <FORCE_GROUP_NAME> path = <PATH> guest ok = no public = no writeable = yes valid users = +GROUP_1 +GROUP_2 vfs objects = full_audit acl_tdb full_audit:prefix = %u|%I|%m|%S full_audit:success = mkdir rename unlink rmdir pwrite full_audit:failure = none full_audit:facility = local7 full_audit:priority = NOTICE Thanks, Sergei> On Jan 7, 2017, at 2:40 AM, Rowland Penny via samba <samba at lists.samba.org> wrote: > > Can you post your smb.conf and raise your loglevel to 10 and post the > relevant logs (probably to dropbox or similar)
