samba - Nov 2019 - get_share_mode_lock: get_static_share_mode_data failed: NT_STATUS_NO_MEMORY

Upgraded to Samba 4.11.2 and I?ve now too started seeing the message:

	get_share_mode_lock: get_static_share_mode_data failed: NT_STATUS_NO_MEMORY

A lot. I modified the source in source3/locking/share_mode_lock.c a bit in order
to print out the values of the service path, smb_fname & old_write_time when
it fails and it seems they are all NULL?


[2019/11/14 14:24:23.358441,  0]
../../source3/locking/share_mode_lock.c:457(fresh_share_mode_lock)
  servicepath=0x0, smb_fname=0x0, old_write_time=0x0
[2019/11/14 14:24:23.358965,  1]
../../source3/locking/share_mode_lock.c:598(get_share_mode_lock)
  get_share_mode_lock: get_static_share_mode_data failed: NT_STATUS_NO_MEMORY


fresh_share_mode_lock() only get?s called from get_static_share_mode_data() when
dbwrap_record_getvalue(rec) returns a value.dptr == NULL.

I?m a bit unsure at the moment if this is a real problem is just an annoying log
entry that can be ignored?

- Peter

Upgrade from samba version? 
OS=? 
Smb.conf content = ? 

These thing do help us in helping to find your problem. 
So can you tell a bit more about the server.

Hai Peter, 

Ok, lets start with,   I know nothing (almost then) about freebsd and zfs.
That said.. .. Ah i see Rowland already replied.. 

I had also a quick peek at the smb.conf

One Rowland missed ;-) 

In this part.

It seems to be the same here since 4.11..:
../../source3/locking/share_mode_lock.c:597(get_share_mode_lock) 

Not sure, if this is related, but it seems we have now much more corruptions on
a
LotusOrganizer-file which is heavily used by some people.
I have to compress often

There is a very good reason why these messages have started to appear 
since 4.11.0, they didn't exist before that version ;-)

As to what the message means ?

I think it just means that a connection failed for some reason, such as 
the share doesn't exist or the user doesn't have the required 
permissions, but to be certain, perhaps the person who added the message 
could clarify this.
