Could not fork

[LeDam]

Hello all...
Sometimes, we have a strange problem with one of our AIX RS/6000 (AIX V 5.2). This server didn't respond with telnet and on the consol, for every commands we enter, we have "could not fork: Not enough space".
So we have no choice...we must reboot the server.
In the log we have :

Mar 25 07:35:23 hn020 prngd[135206]: Could not fork: Not enough space
Mar 25 07:36:14 hn020 prngd[135206]: Could not fork: Not enough space
Mar 25 07:37:57 hn020 last message repeated 2 times
Mar 25 07:38:49 hn020 prngd[135206]: Could not fork: Not enough space
Mar 25 07:40:32 hn020 last message repeated 2 times
Mar 25 07:41:23 hn020 prngd[135206]: Could not fork: Not enough space
Mar 25 07:42:15 hn020 prngd[135206]: Could not fork: Not enough space

On the net i found that prngd was a round number daemon...

Can somebody help me.....

Check your paging space and RAM utilization. AIX will bar new process creation if memory/paging utilization is too high.

I know that...
Why can't root enter any commands?? I thought there is a little paging space reserved for him for this case??

You've got a runaway process (perhaps the prngd process? I don't know what that is.) and need to find out what it is and why it's going nuts. Fix that runaway process and you won't have the problem of not being able to fork a new process.
