openafs used to use a private static pool of inodes.  this was troublesome
due to the number of inode related patches out there.  it seems every
distribution's kernel has a slightly different inode.  as of 1.3.85 we now
use the system inode allocator which should alleviate the bulk of these
problems (it also should cure some race problems regarding management of
a pool of inodes that you want to keep away from the linux kernel).

as for other platforms, i have found the solaris port to always be
rather stable (with a few exception like the afs/nfs translator).
sometimes you need to increase the kernel thread stacksize though.

when was the last time your local news program gave you good news?
