NethServer Version: release 7.6.1810 (final)
Module: Domain Accounts
Since previous update I’m observing a slow/lag in response on the section “Domain Accounts”, I click that and then after some angst moments, this message.
Two days ago if I click on “Samba audit” it shows a blank page, today it shows correctly (I hope)
That other day, this was the load, when it goes to normal I can see the two sections (domain account & sambaStatus):
And this CPU was at full usage that day, but not today:
This NS runs in a proxmox server with ZFS.
This is the load on this proxmox server, it looks normal, on that day I need to reboot twice, the second time I need to stop the vm because it doesn’t reboot
About ZFS file system, I know a little about it, just that it is intensive when it does the scrub, but I don’t see there is big activity daily (need to investigate more on ZFS), the hard disks aren’t fast are RED NAS drives.
What more I can look to detect and fix this behavior ?
The problem is that today, a lot of users included myself, cannot be authenticated and can’t use some services in our lan, mostly ws need authentication to use applications that use sql server.
I reboot the NS and then we can work again, the effect not occur in all, in some other PC it works, but maybe, because the “ticket” was still valid.
Something new in our network, I got a fortinet (FG) that I want to learn how to use, but of course is clean, not have rules just 3 interfaces connected for WAN (internet), one LAN to managed and share the Internet, when I reboot the NS, I disconnect the FG too… Just to explain a little.
Other thing, is that our antivirus (Avast) is updating (new version) and it just create a huge traffic in our lan. The bandwidth is controlled with a trick (using an old software for proxy) just to redirect the upgrade of the antivirus to another PC (not joined in the domain)
This are little details just to be sure.

That Tuesday I read this posts:
After reading this:
I see that LdapURI was empty and manage to fix it. But, the problem remains, even after a reboot of the VM nethserver in proxmox. And after a few hours later the load return to normal.

At this time 20:47, there is nobody at work.
The NS is responding normally … Good! but how/why?
This NS is only used as an authentication, it has some shared folder… I wonder… I wonder if that other module (Samba Audit) is the cause. Yesterday I see a lot of (and I mean a LOT) of pages/records… I take pictures before deleting that logs, and now I see 97 pages from the “24 06:45” to “26 11:15”
So, because I upgrade this Proxmox I will need to shutdown NS and reboot the Proxmox server. (fingers crossed, I’ll report later)
But I will disable the Samba audit of the shares to observe and watch the NS behavior.
---- Edit 4
Systems rebooted, this are the graph of the NS server
So I will see if tomorrow all works as need to be, or maybe just at Monday when all the crew is here.

The module with the huge amounts of logs was “Samba audit” not “SambaStatus”, sorry my mistake.
