Hello
We are running several Red Hat 7 servers as domain members using AD for winbind
idmap backend and it had been working fine (no sssd is configured either)
The last month or so (possibly since the latest samba-winbind package update we
applied on Sep 24), server ssh logins on several servers hang on occasion, until
a winbind restart, when it all works again
Since this is the Red Hat supplied samba-winbind I do have a ticket open with
them but thought I might pose a question here too in case it sounds familiar to
anyone
We ALWAYS see this entry in log.winbindd at the moment the problem happens ..
[2023/10/31 13:51:05.544086, 1]
../../source3/winbindd/winbindd_dual.c:337(wb_child_request_cleanup)
wb_child_request_cleanup: keep orphaned subreq[0x55cbee9dc870]
but, we never see what appears to be the "response", when the problem
does not happen like this ..
[2023/09/06 16:51:23.703029, 1]
../../source3/winbindd/winbindd_dual.c:337(wb_child_request_cleanup)
wb_child_request_cleanup: keep orphaned subreq[0x555c02252ca0]
[2023/09/06 16:52:07.229083, 1]
../../source3/winbindd/winbindd_dual.c:281(wb_child_request_orphaned)
wb_child_request_orphaned: cleanup orphaned subreq[0x555c02252ca0]
One other thing, when the problem occurs, the restart of winbind seems to kill
winbindd processes except one, which hangs out for something like 60 seconds,
then eventually dies and new processes show up
Thanks,
Rob
