Thanks for your response.
This is an OpenAFS 1.2.2 fileserver and we don't have the same host in
the hosttable multiple times - as far as I can see from hosts.dump.

By the way: the fileserver is started with "-cb 65000", the server is=20
heavily used. When ist runs normally we see:

# cbd callback.dump
The time of the dump was 1004438319 Tue Oct 30 11:38:39 2001
The last time cleanup ran was 1004438400 Tue Oct 30 11:40:00 2001
0 add CB, 285715 break CB, 86173 del CB, 34265 del FE, 67359 CB's timed=20
out, 1233 space reclaim, 1786 del host
64015 CBs, 57855 FEs, (121870 of total of 65000 16-byte blocks)

Would it help to increase the "-cb" paramater?

Why is the maximum to "-cb" limited to 65535 ?

Thomas.
