[OpenAFS] Cache size problems on 1.4.1, Solaris 8,9

Hello, lately we've been seeing problems with our cache partitions 
overfilling on our Solaris 8 and 9 machines running 1.4.1.

For example:

%/usr/vice/etc/fs getcache
AFS using 448078 of the cache's available 877506 1K byte blocks.

%df -k /usr/vice/cache
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/dsk/c0t0d0s4    1018382 1012346       0   100%    /usr/vice/cache

%cat /usr/vice/etc/cacheinfo

This problem seems to have started when we switched to 1.4.1.  (I believe 
we jumped versions to get to 1.4.1, so the problem may have appeared in an 
earlier version...)

The only solution we've found is to reboot the troubled machine, after 
which the cache behaves normally.  I have not yet been able to determine a 
set of conditions that cause the cache to overfill, we've just been 
kicking the machines as we find them.

Any clues?
