POSKeyError on Interface tab on certain device

I get this stacktrace in zenhub.log:


2014-04-22 14:16:50,042 ERROR zen.hub: Unhandled exception in zenhub service Products.ZenHub.services.PingPerformanceConfig.PingPerformanceConfig: 0x19c4e1

I have tried to restart zenoss, restart memcached, restart mysql.

Also tried to run through all tips here: http://wiki.zenoss.org/Fixing_ZODB_Integrity_Issues but even the last zenoss-repairdevice.py fails with

So now I'm very lost... anybody got an idea of how to fix this issue

Running on Zenoss 4.2.4 on Centos, and this error appeared a few days ago.
