Hi all!
No, I'm not exporting any ISO fs over NFS anymore, sometimes I do, but then only for a couple of minutes and then I exportfs -u the exported mount point.
I thought it was a heat problem, since I was running dnetc on an AMD which gets very hot, but I had the same OOPS yesterday, this time only on nscd (dnetc was also running, so load was at 1).
Everything seems to continue running after nscd oopses, but logins are impossible, so the machine needs to be rebooted.
Here the last nscd oops:
