All nodes are working if you don't get error messages. You can monitor the job in Director choosing the "Show Instances" option to get row counts and CPU usage on a per-node basis.

Try the below command in unix box & check the maximum number of process allowed per user. If the value is less than 100 inform your Administrator to increase the value.

lsattr -E -l sys0 | grep maxuproc

is there a linux equivalent to that?

Ernie - I know that there is, but I seem to recall it is different on different versions on Linux as well.

Scope/krishna - The fork failed error is certainly caused by a setting of maxuproc too low, but a value of only 100 is far too little for PX to work; even a medium sized job with several nodes will blow that limit. A value of 1000 or 2000 is more appropriate.
