Moved my production over to kerberos this morning with the correct export for kerberos and this is whats happening 20711 squid 20 0 32212 3748 1732 R 34.3 0.1 0:04.42 squid_kerb_auth 20716 squid 20 0 32200 3748 1732 R 34.3 0.1 0:08.41 squid_kerb_auth 20712 squid 20 0 30544 2196 1732 S 20.6 0.1 0:28.23 squid_kerb_auth They are just the top 3 processes. When i am not using kerberos authentication my cpu is hardly touched. Any insight would be awesome.
