It depends upon your OS, but for 11i look at these kernel parameters:

nkthread
and
max_thread_proc

live free or die

Hi

As harry has mentioned, check the nk_thread value and you have to increase it. But before that , you can check for any dfunc process which is created this mess...

# ps -ef | grep defunct

and kill these PID's and this will clear your problem.

Sameer,

How long has ur system been up.

Check out your CPU & memory usage using TOP if your system has been up for a long time, and also verify the time how long the processes have been running on the box. You will be able to see all of this info through the "top" command.

If your system has been rebooted recently, you may increase the kernel parameter as told by others above ( i won't repeat the same). Mostly, this error is due to limited threads configured on your system, or it will be due to defunt processes on your system in a hung state.

Regards,
Anil
