"inode: table is full" - a question

[alex at lancelot]

From: Alex Bronstein <alex at lancelot>

Hello,

	Someone called me and told me that his VAX is suffering from 
the following symptoms:

The message: "inode: table is full" keeps being printed on his console.

I have tracked that down to iget() in /sys/sys/ufs_inode.c, but there
is no comment as to the likely cause (or fix) for this problem.
(I.e. should he recompile his kernel with a bigger constant somewhere,
buy more memory ?)

The only other information I have is that there are 2 disks on the
machine (ra81s I believe) and 10 days ago, they hooked up an
"Interlan net", the problem got worse after that.

	Has anybody around here ever encountered a similar problem?
Does anybody immediately see what's going on?

	Thank you,

				Alex
