Dead processes

[peterchu]

Our system has limit the no. of concurrent login , it only allow 300 users can access the system at the same time , but sometimes I found there are dead processes in the system ( due to different reasons ) , so that the users can't access to the system when the total no. of login not reach to 300 , how can i prevent it , how can I kill the dead processes ? please suggest , thx in advance.

hi,

could you reply the output of the following kernel parameters:

# kmtune -q nproc
# kmtune -q maxuser

also, what is the dead processes, e.g defunct? you may use kill command, e.g.

# kill -9 `ps -ef|grep 'defunct'|grep bin|awk '{print $2}'`

regards.

Peter,
I agree with Joseph's suggestion

I think you might be referring to defunct processes on your unix system. If that is the case then you may use

kill -9 pid

As a word of caution, if you are not very familiar, throw the output requested by Joseph and we can look at that and let you know if those could be killed
