The problem is that the zfs cache in the kernel we are using has a memory leak which results
in memory getting low after a couple of month. We cannot patch the system as the newer
kernel also introduces a new libc which makes it harder to build packages for older
versions of Solaris, so we must stick to it. The solution is reboot the machine every couple
of month if it gets too slow. The solutio0n is to drop me a note when the responsetimes
become unacceptable, sorry :-/

I am currently on vacation with limited connectivity.
@Jan: Can you please reboot the 5220 sometime?


Best regards
