Testing on the other instance on:
Yes and I have some reruns on various other machines going now as part of triage efforts, and will update the issue once results are in.
NoRouteToHostExceptions also seen on test-marist-sles15-s390x-2 - see https://ci.adoptopenjdk.net/job/Grinder/6086/
Those types of exceptions are not seen on test-marist-ubuntu2204-s390x-1, but other problems on that machine... issues appear to be mainly related to tests using multicast addresses. https://ci.adoptopenjdk.net/job/Grinder/6087/testReport/

I have a fix I can try on there relating to the firewall configuration - this only occurs on the new Marist machines we've got and will allow multicast to work based on past experience - applied on the ubuntu2204-s390x-1 machine referred to above and regrinding at https://ci.adoptopenjdk.net/job/Grinder/6103/ to test
iptables -I INPUT -m pkttype --pkt-type multicast -j ACCEPT
[EDIT: This has resolved the problem - everything in java_net passed, although https://ci.adoptopenjdk.net/job/Grinder/6103/testReport/tools_jlink_JLinkReproducibleTest/java/JLinkReproducibleTest/ failed which is not likely to be related to this issue]

I'm going to re-grind that one after removing a someone rogue entry in /etc/hosts
- I don't /think/ it will have made all those fail, but we'll see - depends exactly what the tests are doing in terms reverse host lookups ... https://ci.adoptopenjdk.net/job/Grinder/6104/ - If not it's going to need someone to do somre more low level debugging.
[EDIT: As expected no real change - [https://ci.adoptopenjdk.net/job/Grinder/6086/testReport/java_net_httpclient_http2_TLSConnection/java/TLSConnection/] passed in the new run, but that may have just been luck]

The above analysis suggests that we can resolve a lot of the issues on the RHEL/SLES systems by performing a similar firewall fix to assist the multicast packets to get through. It will be interesting to see how many other problems remain after doing that.
Bear in mind that many of the offline machines are the older ones which were replaced during September as part of the Marist machine migration which we have done, so that is expected (They've been offline in jenkins for a while, but now need to be fully removed)
Of note is that they do not appear as "offline", https://ci.adoptopenjdk.net/label/hw.arch.s390x&&ci.role.test/ shows
where I would have expected to see the red X as with some other offline nodes:

@andrew-m-leonard
test-marist-sles12-s390x-2 still a problem: https://ci.adoptium.net/job/Test_openjdk17_hs_extended.openjdk_s390x_linux_testList_0/86/
I had a look at this machine earlier this week, and disabled it... the network issues are fairly extensive, and the workaround doesn't appear to work, so it needs some more investigation and work.

Labelling with systemdown
on this basis
@steelhead31 Is this something that will be fixed by the hostname changes you're putting in place or is it a separate routing problem?
This is a seperate routing problem, Its unlikely my PR will fix this, but if we manage to find a suitable fix, that should persist, thanks to my changes.
@steelhead31 Can you take a look at this and see what would be suitable as some "next steps" to move this one forward please? It does look from the table in anearlier comment as though we may have failures almost everywhere (although I wonder what's happening in the docker containers...)
Have narrowed down the error to this piece of code..
try {
csoc = new Socket(InetAddress.getLocalHost(), port);
} catch(Exception e) {
System.err.println("Failed. Unexpected exception:" + e);
throw e;
}
Update: This issue (or something like it) is still seen.

After a number of NoRouteToHostExceptions in other targets, the jdk_jfr_1 target appears to cause the entire job to fail, and I'm guessing it's related to this issue.
Have the other jobs associated with this issue failed as well? As in non-"unsafe" failed. Jenkins red job failed.
Let's check if the outstanding problems are only on the SLES12 systems and whether they also occur in the docker SLES12 images that we have.
March JDK22 release activities Grinder/9226 50 compiler testcases fail with no route to host issues on test-marist-sles12-s390x-2
FYI @steelhead31
A little more narrowing down may be useful to verify the systems it's running on and then decide whether we need to continue supporting them, and potentially raise with Marist if it is across the board on all machines.
It's been a while so time for a new table!

Based on the above it's entirely possible that the subject message is only applicable to test-marist-sles15-s390x-2 now, and the others should be covered under separate issues ... Although based on https://github.com/adoptium/aqa-tests/issues/5156#issuecomment-2008023921 I'm going to try and run the whole of extended.openjdk on this machine to see if it hits any of these errors elsewhere in the compiler suite: https://ci.adoptium.net/job/Test_openjdk21_hs_extended.openjdk_s390x_linux/81/
Noting also that test-marist-rhel7-s390x-2 has been taken offline due to these exceptions so is not included in the above tests. Memo to self: iptables suggestion that worked on some machines previously is at https://github.com/adoptium/infrastructure/issues/2807#issuecomment-1301484486
