1407: NFS problems under investigation

When we moved the gateways of our networks from the old location to the new firewalls, we have received some complaints about NFS filesystems having slowness, longer delays or unavailability. In general NFS should never be a requirement for a clusternode job if you can avoid it, because this I/O is always much slower than local I/O from /scratch. We are investigating how we can optimise the network to resolve this issue, but we are hard pressed to know the exact cause of the problem....

1137: SMTP server problem because of too short keys

Starting a month ago, mail programs could get an update due to the vulnerability for a LogJam attack. After this update these programs refused connections with a server with a too short key. The old C&CZ authenticated SMTP server had such a short key. Users who reported this problem (with the latest versions of Pine, Thunderbird and recently also Apple Mail), were advised to temporarily use an alternative server. As of today using this alternative server is no longer necessary, because the server smtp....

1132: Ubuntu 10.04 cluster / cn99 server problem

The server (cn99) which serviced SUN Grid Engine on Ubuntu 10.04 is no more. It could not find its disks while booting. This will not be solved because the machine is already more than five years old. Clusternodes cn67, cn74, cn75 and cn81 are influenced. They can still be used by logging into them directly.
