Description of problem: We installed a fresh RedHat AS 3 for s390x downloaded from RHN. This system showed strange effects. sshd was running, because we can login to the guest via ssh but ps does not list the sshd. Same effect with cups and sendmail. We could talk to them but they are not listet with ps. netstat shows that the ports are used by programs with unknown pids. Only a few pids are listed in /proc. The listed pids are shown in ps and netstat. What processes are shown depends on memory size of the guests. This is for example the one were sshd is shown but no cups: [root@li010 proc]# ps aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.2 1720 624 ?
