Re: Re:migrating, load-balancing, 2.4.26, 2.4.24, Virtual PC

Thank's a lot.
your perl script works. So there seems to be problem with migrating shell 
scripts.

Unfortunately one other problem ist still left. In 1 out of 20 cases the 
script returns a memory error instead of returning results. (<- I added a 
line with print $i and changed the while statement to $i<100000)
