[Stefan Priebe - Profihost AG]

HI,

an additional note:
   ¦   +-sshd,5635
   ¦       +-qm,5637 -w /usr/sbin/qm start 100 --stateuri tcp --skiplock
   ¦           +-(qm,5638)

root        5635  0.0  0.0  70456  3340 ?        Ss   15:07   0:00 sshd: 
root at notty
root        5637  0.1  0.3 174996 26372 ?        Ss   15:07   0:00 
/usr/bin/perl -w /usr/sbin/qm start 100 --stateuri tcp --skiplock
root        5638  0.0  0.0      0     0 ?        Zs   15:07   0:00 [qm] 
<defunct>


so qm is defunct - sadly i wasn't able to find out why.
