Define problems.
I once used nessus to do some auditing on one of my server networks. It
caused one server app to crash due to the application expecting a
specific communication string when a system connected to it. It could
be that they are running a really poorly written app that expects
specific connection strings and nmap sent something it did not
like/expect.
Can you query the admins and ask them if the problem seems like a system
problem or an application problem. I have a feeling it's an application
issue and not a system issue.

Subject: Dangerous in using nmap for AS/400 730 machine configured with
3 ASPs?
Peace all,
I am wondering whether this is related or not.
I was in the middle of beginning a pentest activity for a network
segment containing quite a number of AS400 (Production).
I started with a simple nmap first to see what I am facing.
My command was (IPs are masked) "nmap -sV -vv -p 8470-8476 -o
firsttry_port.nmap xxx.xxx.xxx.0/24"
This lasted for about 15 minutes.
After about 2 hours later, 2 out of 50+ identifiable machines started
having problems.
They became very slow.
Those two machines are using ASP (Auxiliary Storage Pools), 1 ASP on the
1st machine and 2 ASPs on the 2nd.
I just want to get more information whether my nmap did anything "bad"?
:)
Thanks and Regards,
