[OpenAFS] Fileserver very busy

[Hans-Gunther Borrmann]

Hello,

I observe that one of my fileservers is very busy over long periods of time, 
everal days or even a week. tcpdump on the fileservcer only shows the 
following traffic;

16:09:12.981900338 server.afs3-fileserver > client.afs3-callback: udp 66
16:09:12.982000367 server.afs3-fileserver > client.afs3-callback: udp 32
16:09:12.982190070 client.afs3-callback > server.afs3-fileserver: udp 44
16:09:12.982315764 server.afs3-fileserver > client.afs3-callback: udp 32

16:09:12.982622973 server.afs3-fileserver > client.afs3-callback: udp 32
16:09:12.982808396 client.afs3-callback > server.afs3-fileserver: udp 44
16:09:12.982934593 server.afs3-fileserver > client.afs3-callback: udp 32

16:09:12.983247845 server.afs3-fileserver > client.afs3-callback: udp 32
16:09:12.983437670 client.afs3-callback > server.afs3-fileserver: udp 44

fstrace on the client shows only the following:
