I don't know = why, because audit_read _looks_ like it's doing the right thing. Symptoms: 1) Sending SIGTERM to auditd doesn't kill it right away; you might send SIG= TERM and then send a trigger with auditon(2). 2) Same with SIGHUP 3) Zombie child processes don't get reaped until auditd receives a trigger = sent by auditon. This includes children created by expiring audit trails at aud= itd startup. --=20 You are receiving this mail because: You are the assignee for the bug.=
