** Description changed:

  There is a big memory leak bug in Samba 4.1 - 4.7.6. Depending on the
  circumstances all memory of the Ubuntu server will be eaten by Samba
  sooner or later. Then Linux Oom - killer will kill Samba which will
  either restart or hang.
  
  On our Ubuntu Server 14.04.5 I need to restart Samba 1 - 2 times a week.
  This bug probably affects also Ubuntu 18.04 if this fix has not yet been
  backported.
  
  This bug has been fixed upstream in Samba 4.7.7. The fix is only two
- lines of code and is caused by a misplaced "if" when releasing memory.
+ lines of code and the bug is caused by a single misplaced "if" when
+ releasing memory.
  
  This upstream commit fixes the bug: https://gitlab.com/samba-
  team/samba/commit/461a1172ff819692aa0a2dc5ce7fc5379c8a529e
  
  This is the Samba bug report:
