    Ok.

    I've backtracked the problem and identified that the cause is:
~~~~
afsd -dynroot -afsdb -memcache -dcache 8192 -chunksize 14 -stat 32768
-fakestat-all -daemons 6 -volumes 256 -nosettime
~~~~

    Because if I remove all the "fine-tuning" it works as:
~~~~
afsd -dynroot -afsdb -memcache -fakestat-all -nosettime
~~~~

    But still, should the cache manager crash the system if badly configure=
d?

    Ciprian.
