If you check the log fragment the OP provided:

2019-11-28T20:40:44+01:00 lx-sv-09 smbd_audit: [2019/11/28 

It tells you where to search in Samba git: 

So, if you follow the path provided:

source3 --> locking --> share_mode_lock.c

You can then open 'share_mode_lock.c' in your favourite editor and go to 
'get_share_mode_lock' and then look for the error message, in this case 
'get_static_share_mode_data failed'. This also returns 'nt_errstr' from 
'status' and this comes from 'status = get_static_share_mode_data(' . In 
this case, it returns 'NT_STATUS_NO_MEMORY'.

Now you know where it comes from, you can check the history for 
'share_mode_lock.c', this is where I found this:
