[Bug 1010045] Re: 12.04 hangs on shutdown deconfiguring network interfaces
I'm now thinking of going back into this issue. Definitely the problem appeared when installing cups as it requires avahi+mdns packages. This sounds quite fair if cups is to autodetect printers in the LAN. I've been reading more about mdns. I remember that previously I removed it in certain host to avoid delays in SSH connections and now I have been reading again about it at bug #94940 https://bugs.launchpad.net/ubuntu/+source/nss-mdns/+bug/94940. If the delay is caused by mdns it may be amplified when having an interface configured as multiple VLAN sub-interfaces. Cheating nsswitch.conf sounds easier than completely removing avahi+mdns... So, I would like to know if the rest of the people have avahi+mdns installed and what does their host entry in nsswitch.conf look like. I'm quite confident that keeping hosts: files dns as it is now (with avahi+mdns uninstalled) may help in my case. We also have a MS AD with a .local private domain but I doubt this may interfere as both AD servers switch off every day a couple of minutes before our Ubuntu host does. ¿Do you have .local AD in your LANs?

[Bug 1010045] Re: 12.04 hangs on shutdown deconfiguring network interfaces
:-)) Seems to be fixed. It was an old friend of mine... I removed much software installed during the last week. But only after this one I got the shutdown in time. Boot process seems to be faster now and a lot of OpenSSH start/stop messages are gone: sudo apt-get purge avahi-daemon libnss-mdns It's about Zeroconf and APIPA IP numbering, but I don't think it is necessary for desktop servers. So, I'll try to reinstall things and get my system back to production. On the other hand, I still don't understand why this didn't bother us a couple of weeks ago...

[Bug 1010045] Re: 12.04 hangs on shutdown deconfiguring network interfaces
We have been preparing this machine for about a year. It is supposed to work as a a firewall and web proxy connected to about 10 vlans, with DNS server, LAMP, Squid, etc. It's a 64 bit Ubuntu Server perfectly up-to- date. One week ago we decided it was finished and we moved it into production use. To this point everything was OK. During the last week we configured samba + swat - libpam-smb + cups + hplip and there was a kernel update: on Monday we noticed the hang at the Deconfiguring network interfaces but yesterday we saw that it was not a real hang because the system powered off in about tree-four minutes (it used to be about 20-30 seconds). I have just removed cups + hplip with no success. My next plan is to remove the samba set (I was suspicious of the problems between swat and libpam-smb) and maybe go back to previous kernel as this was the whole story of the last week. Here, above, I saw some relation between the length of the delay, the point where it happens and the number of interfaces, so I'm writing about it. I may try to add some verbosity, but I have very little clues... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1010045 Title: 12.04 hangs on shutdown deconfiguring network interfaces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1010045/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1010045] Re: 12.04 hangs on shutdown deconfiguring network interfaces
@stgraber That's oversimplifying things a bit. :) As the OP, our servers have several interfaces which gives a server access to various subnets. One of these holds the ldap auth servers. If this interface is downed first, resolvconf will hang for ldap.conf TIMEOUT time for every other interface downed. When they're all down (or any default or matching subnet routes), resolvconf/getent passwd returns immediately. So... In my case, reducing the /etc/ldap.conf /etc/ldap/ldap.conf timeouts or adding a blackhole route with a high metric value matching the ldap subnets would work around this. As such it can't be categorized as a bug. When I initially chimed in, the problem was masking the infamous scsi kernel softlockup bug. I'm still puzzled over the nss query resolvconf is triggering. I cannot reproduce it with getent password or similar lookups. For whatever reason resolvconf triggers a query looking for a posixaccount with uid=\2a (uid=*), which returns 0 results. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1010045 Title: 12.04 hangs on shutdown deconfiguring network interfaces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1010045/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1010045] Re: 12.04 hangs on shutdown deconfiguring network interfaces
Right, so we appear to have a few things going on here: - People using networked auth in blocking mode - People using an iscsi root that for some reason isn't brought up correctly and that ifupdown tries to kill Those two are likely configuration mistakes as you should never configure a network nss plugin to be blocking, otherwise your boot and shutdown sequence may randomly hang. Instead, there are flags to make the calls immediately return when there's no route available. Anyone is having this bug and isn't part of one of the scenario above?

[Bug 1010045] Re: 12.04 hangs on shutdown deconfiguring network interfaces
Resolvconf seems to be causing the hang in at least one of my
testcases. It seems to be attempting to speak with our ldap
authentication servers. Strace shows it is trying to lookup the
hostnames of the auth servers and the connect to them multiple times for
every interface, making the shutdown process take a very long time.

Same for my system. If i start /etc/init.d/networking stop or ifdown -a directly, it is working... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1010045 Title: 12.04 hangs on shutdown deconfiguring network interfaces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1010045/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1010045] Re: 12.04 hangs on shutdown deconfiguring network interfaces
Hello Stephane, Thanks for the feedback. I attached the tar of /var/log/upstart. The vm from where i created the tar, doesn't use NFS nor other network attached shares.

[Bug 1010045] Re: 12.04 hangs on shutdown deconfiguring network interfaces
Can you attach a tarball of /var/log/upstart? Is that machine relying on nfs mounts?
