Systemfunc error

Hi all.

In my batch visualization script, that runs during the night to produce
a lot of pictures, it happens sometimes this strange error:

fatal:systemfunc: cannot create child process:[errno=12]

during the call to these simple "log" procedure:

; add date and time string to console output
procedure _log(s:string)
begin
  print(systemfunc("date +%F' '%T") + " " + s)
end

The error is strange. In fact, if i restart the code, it can runs fine,
or crash again. But i can not understand why.

Do you have suggestions for me ?

Thanks a lot, Marco
