I-node table

4.2BSD:
Our inode table is losing slots. pstat normally goes through the
inode table sequentially, reporting only on those slotw with non-zero
reference counts, and assumming that the others are free. I modified
pstat to walk through the free list, printing the addresses.
Yesterday, just after a reboot of our VAX 11/785, I got a healthy
report, something like 129/788 active inodes, 659 in the free list.
This morning, I looked again and got 165/788, 456 in the free list -
165 + 456 = 621. Arggh. I started looking at this because we've been
getting "inode table: full" messages on the console, and the pstat at
the time told me there should have been ~600 free.
I've got the bug list from Mt. Xinu. A few of the messages have to do
with the inode table, but none directly with the symptom of a
corrupted free list. I'll be installing those fixes one at a time
until the problem goes away, from simplest to most complex. Meanwhile
I appeal to the net, asking if anyone has a better guess as to what's
plaguing us.
Thanks in advance,
