[Samba] Defunct processes on solaris 10

[Jeandre Le Roux]

Hi,

I'm getting a few defunct processes running samba 4.4.16. They tend to
accumulate over time, however they dissapear after I do a `svcadm
restart samba`. Samba is joined to an AD domain.

Sanitized global section of smb.conf:
[global]
        dedicated keytab file = /etc/samba/krb5.keytab
        idmap config * : backend = tdb
        idmap config * : range = 10000-50000
        kerberos method = secrets and keytab
        log file = /var/samba/log/log.%m
        log level = 3
        max protocol = SMB2
        min protocol = SMB2
        realm = xxxxx
        security = ADS
        server signing = auto
        server string = xxxxx
        usershare allow guests = Yes
        winbind enum groups = Yes
        winbind enum users = Yes
        winbind refresh tickets = Yes
        winbind use default domain = Yes
        wins proxy = Yes
        wins server = xxxxx
        workgroup = xxxxx
        deadtime = 1
        debug pid = yes

When I search for the pid of one of the defunct processes I find that
the log file ends with :
[2018/10/30 15:03:49.477853,  2, pid=20630] ../source3/smbd/process.c:2875()
  Closing idle connection
[2018/10/30 15:03:49.479553,  3, pid=20630] ../source3/smbd/server.c:154()
  got a SHUTDOWN message
[2018/10/30 15:03:49.480308,  2, pid=20630] ../source3/smbd/service.c:1063()
  10.20.35.219 (ipv4:10.20.35.219:62304) closed connection to service DATA12
[2018/10/30 15:03:49.481689,  3, pid=20630] ../source3/smbd/server_exit.c:246()
  Server exit (normal exit)

Is there any other info I can provide that can help, or any advice?
