From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 CentOS/1.7.12-1.4.1.centos4 Description of problem: When upgrading to openssh-server-3.9p1-8.RHEL4.9 from an older version using yum, the preinstall script: preinstall scriptlet (using /bin/sh): /usr/sbin/useradd -c "Privilege-separated SSH" -u 74 \ -s /sbin/nologin -r -d /var/empty/sshd sshd 2> /dev/null || : runs useradd which sits in a tight loop using up CPU. This process also cannot be killed even with a kill -9. This only happens on x86_64, and not i386. I have duplicated this 3 times on 3 different x86_64 installations Version-Release number of selected component (if applicable): openssh-server-3.9p1-8.RHEL4.9 How reproducible: Always Steps to Reproduce: 1. Upgrade RHEL from 4.1 to 4.2 on x86_64 Actual Results: useradd sits in a tight loop using cpu, and the yum upgrade will not continue. Expected Results: the package should have been upgraded normally Additional info:
1. Upgrading RHEL using yum is not supported. 2. This is definitely not a bug in openssh. 3. This is most probably some problem with kernel and upgrade of auditd. 4. Try to upgrade the kernel first.
