Looking for job which is causing a large work load

[Margaret Doll]

I found the zombie to be

F S   UID   PID  PPID  C PRI  NI ADDR SZ WCHAN  TTY          TIME CMD
4 Z    99  5334  5209  0  75   0 -     0 exit   ?        00:00:00  
dnsmasq <defunct>

which was started by

root      5209     1  0  2009 ?        00:00:00 libvirtd --daemon
nobody    5334  5209  0  2009 ?        00:00:00 [dnsmasq] <defunct>

I also found 622 cat programs in a sleeping state

root      2213  2211  0 Feb02 ?        00:00:00 cat /sys/hypervisor/uuid
root      2244  2242  0 Feb11 ?        00:00:00 cat /sys/hypervisor/uuid
root      2297  2295  0 Feb14 ?        00:00:00 cat /sys/hypervisor/uuid
root      2314  2312  0 Feb07 ?        00:00:00 cat /sys/hypervisor/uuid
root      2350  2348  0 Jan29 ?        00:00:00 cat /sys/hypervisor/uuid
