:Hi,
:
:It seems that kern/32672 is not fixed yet on FreeBSD 4.5-STABLE.
:
:System 4Gb RAM, 4x700MHz
:
:When the system is not using all RAM, the FFS node memory grows up to a
:limit of 102400K which leads to a system deadlocking.

    Well, there was some further work done to the vnode reclamation
    code after the 4.5 release.  RELENG_4_5 has 1.249.2.23
    RELENG_4_6 has 1.249.2.27.  Peter Wemm introduced a major upgrade 
    to the vnode reclamation in 1.249.2.24.

    I don't think I can really go back and backport this stuff to the
    4.5 branch.  If you upgrade to 4.6 or 4.7 and still have the problem
    I can look into it (the differences in this particular area of code
    between 4.6 and 4.7 are minor and it would be easy to make fixes in
    both branches).
