Greetings,
I have SAMBA4 AD DC running on Debian 11
with samba backports running SAMBA Version 4.17.12-Debian
It seems after 55-65 days uptime I get out of memory error.
Any thoughts on what to check? This is a virtual machine with 3.8G.
After a fresh restart of SAMBA here's the memory usage:
total used free shared buff/cache
available
Mem: 3.8Gi 377Mi 3.3Gi 2.0Mi 201Mi
3.2Gi
Swap: 0B 0B 0B
Do I need to add a swap file?
It's not a particularly busy server with less than six active users.
I have a second domain controller in the same domain with only 2G RAM.
After 55 days of uptime memory usage = 708MB, this server however is
not running DHCP server.
I just increased the dhcp lease time on DC01 to 17hrs, where it was
five minutes. The logs were pretty active with DHCP lease info.
Here's some info that might help identify any misconfiguration.
Thanks in advance for taking the time.
Cheers!
Eric
