Comment # 84 on bug 1017461 from Gerald Weber

I am experiencing a similar problem on a freshly installed Leap 42.3. 

The btrfs-transacti process makes the system completely unresponsive for about
10 to 15 min. It happened already 3 times since the install 3 days ago, that
is, typically once a day. I am correlating this with the automatic software
update which apparently triggers snapper into action and then btrfs. I have
changed the software check to happen only once a month to see if it eases the
problem, but I would welcome any other workaround as this is being very
disruptive.

The machine is a Dell Inspiron  Inspiron 5448 and has as disk a Samsung SSD 850
EVO 1TB.

I am happy to provide more system info or do some tests if it is of any help.
