izvrsavanje komandi na sistemu (linux), zombi problem

izvrsavanje komandi na sistemu (linux), zombi problem 29.06.2005. u 11:44 · pre 259 meseci #1

koristim komandu ping koju pozivam sa:

Code:
ping = popen( &komanda[50] ,"r");

i to se vrti u petlji za svaku adresu koju provjeravam.

problem je ovo:

Citat:

milan 57485 0.0 0.0 0 0 p0 Z 11:30AM 0:00.03 <defunct>
milan 57487 0.0 0.0 0 0 p0 Z 11:30AM 0:00.02 <defunct>

ovakav po jedan se stvara za svaku ip adresu koju provjeravam

i top prikazuje ovo:

Citat:

50 processes: 2 running, 32 sleeping, 16 zombie

ubacio sam fclose, ali opet isto...

kako da sprecim stvaranje ovakvih zombi procesa?
