Took initial look and the issue seems like samba upstream BZ https://bugzilla.samba.org/show_bug.cgi?id=12372 . This may be only one part , rest needs to be looked at. How is this different from bug #1400957 ? (In reply to Michael Adam from comment #4) > How is this different from bug #1400957 ? More precisely: The steps to reproduce are exactly the same! And they both claim to be always reproducible. But the effects are *different* BTs. That's why I am confused.

Looks like i missed to mention that this bug #1400948 is found in SSl enabled setup. Enabled for management & IO. #1400957 : Is reproduced on a non ssl enabled set up. This is the only difference. Upstream fix: https://git.samba.org/?p=samba.git;a=commit;h=4194c0797f78293fe48105ce5af70f36a3c233a8 On the build provided in #C11 tried the test case mentioned in bug description and the core mntioned in the BZ is not seen. Tried following: 1. Start i/o's from windows client. (10000 byte files) with vip 1 mounted share 2. ctdb stop on node1 , wait for it to go to stop , ctdb stop on node2,then on node 3 . keep watching failover and then stop on othe rnodes. 3. restart ctdb service on each node one by one. 4. verify I/O's are running and there are no cores. tried few more scenarios with multiple stop and restart options. The cores mentioned in bug description is not seen , however saw multiple cores getting generated with ctdb restart on node1 with the bt mentioned in BZ https://bugzilla.redhat.com/show_bug.cgi?id=1400957. After reboot the issue is not seen. Will discuss more with rhs-smb team and take action on another bZ. This bz seems to be fixed with above build. Version ---------- samba-client-libs-4.4.6-4.el7rhgs.x86_64 glusterfs-cli-3.8.4-10.el7rhgs.x86_64 Followed the above mentioned steps to reproduce did not find any cores. No issues faced. Marking it as verified. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
