OK, Thanks for your information. If I remove this new group with 3500 users, I understand that load will be recovered to normal usage, correct? About upgrade if I have only one server with 4.4.5 the best option is add another dc with 4.7 compiled, then transfer and upgrade (or join old server) or upgrade actual 4.4.5 to 4.7 and then add a new dc? I like to keep 2 dc with same config and fully compatible and stable Thanks 2018-02-13 23:40 GMT+01:00 Andrew Bartlett <abartlet at samba.org>:> On Tue, 2018-02-13 at 23:31 +0100, Trenta sis wrote: >> Hi, >> >> First of all thanks for your answer, today has increased cpu usage, >> only change is add a new group with 3500 users, It could be the >> problem? > > Yes, that will do it.

In Samba 4.4 that won't help, the group and the group memberships will remain, just marked as deleted.> About upgrade if I have only one server with 4.4.5 the best option is > add another dc with 4.7 compiled, then transfer and upgrade (or join > old server) or upgrade actual 4.4.5 to 4.7 and then add a new dc? > I like to keep 2 dc with same config and fully compatible and stableDo the upgrade by joining a new DC, don't upgrade in place. Remember you will have to replicate the sysvol contents yourself however. That also allows you to upgrade the base OS, which is likely getting old in any case.

Hi,

upgrade from 4.4.5 to 4.7.5 directly or requires other upgrades...
