** 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.
