Anyone else experiencing high rates of Linux server crashes during a leap second day?

The process ksoftirqd/0 uses permanent 15% CPU on our debian squeeze server. 

4 root      20   0     0    0    0 R 15.0  0.0 850:59.17 ksoftirqd/0

I already read that this can have various reason like Full harddisk or high network traffic. In our case we do have more or less low network traffic and enough space on hard disk. How can I analyse what causes ksoftirqd/0 to use permanently 15% CPU?

If ksoftirqd is taking a considerable percentage of CPU time that indicates the machine is under heavy interrupt load. This is one of the leap second problem symptoms , you might want to check:
