Title: High CPU - Samba
Post by: johan.badenhorst on January 06, 2020, 08:46:55 am

Since the upgrade to Zentyal 6.1.2 I noticed a very high CPU usage by samba

Any idea what may be causing this?

There isn't any reason for it. Usually, it's due to the log level defined for the vfs audit. https://www.samba.org/samba/docs/current/man-html/vfs_full_audit.8.html (https://www.samba.org/samba/docs/current/man-html/vfs_full_audit.8.html)

You can check your log level with the samba testparm tool or viewing your smb.conf file:

Code: [Select]

...
force create mode = 0660
force directory mode = 0660
path = /home/samba/shares/test
valid users = "@Domain Users"
vfs objects = acl_xattr full_audit
write list = "@Domain Users"
full_audit:failure = connect opendir disconnect unlink mkdir rmdir open rename


Remeber that you don't have to modify this file directly, but through the zentyal templates (read this: https://doc.zentyal.org/en/appendix-c.html#stubs (https://doc.zentyal.org/en/appendix-c.html#stubs))

Cheers!
