This is an F540 running 5.2.1P2D14 The filer is basically doing nothing - but every 5 seconds or so the CPU goes up to 80 or 90% and stays there for 6 or 7 seconds.
We've been having trouble with systems that have NFS mount to this filer hanging. The only solution (thus far) has been to reboot the filer.
I'm not too worried about it because this system was due to be replaced this Sunday, but it'd be a good one for the data banks if anyone knew what caused this type of behaviour.
sysstat is below.
Thanks, Graham
