Yep, that's it exactly, kernel memory leak that doesn't appear to be
allocated to anything and a reboot to fix it. And yes, we're using
A1000 RAID devices for our storage, attaching to the raw disk slice for
CNFS spools.
So, do I take it the solution will be to mount the disks as part of the
regular file system and create files for the cyclical spool to store
articles? Will this still require new A1000 drivers from SUN, and if so
do you know which version (as a minimum) fixes the problem?
Thanks for the help Russ, I'm very glad someone else has seen this
before
