From the same point of view, the default value of forkrate should be
no limit. (In addition, 1 million tasks per hour is not an abnormally
high rate.)
It is quite high. however, in some applications I can immagine that a
machine would indeed trigger a very high fork rate.
For example, a machine that runs lots of shell scripts that call each
other, may all of a sudden be forking the required 300/second....
I agree that it is quite high rate. However, as you pointed out,
shell scripts may fork processes in very high rate.
Another reason I don't like this default values is that
forkrate_interval is too long.
Please imagine if forkrate limite is reached in the first 30 minutes,
we cannot fork any process for another 30 minutes. It is not what
I expected.
Thanks,
