[Samba] smbd's using up 100% of all cpu's and load avg slowly going up
Hi, I'm having problems in a second domain controller machine. Every time a restart samba, few time after a samba process starts using almost 100% cpu. It's a Centos 6.5 x86_64 with the following: sernet-samba-libsmbclient0-4.1.6-7.el6.x86_64 sernet-samba-ad-4.1.6-7.el6.x86_64 sernet-build-key-1.1-4.noarch sernet-samba-libs-4.1.6-7.el6.x86_64 sernet-samba-client-4.1.6-7.el6.x86_64 sernet-samba-4.1.6-7.el6.x86_64 sernet-samba-common-4.1.6-7.el6.x86_64 sernet-samba-winbind-4.1.6-7.el6.x86_64 The testparm outputs the following: Load smb config files from /etc/samba/smb.conf Processing section "[netlogon]" Processing section "[sysvol]" Processing section "[Profiles]" Processing section "[home]" Loaded services file OK.
