Lester:
Some things which would be helpful to know:
* what version(s) are the AFS servers?
* what version(s) are the AFS clients?
* does the firewall allow arbitrary UDP packets to be sent to internal IP addresses on port 7001?

Hi All,
I've been having an issue with some clients no longer being able to access a fileserver when the server is put under a high load, typically by transferring many small files. It's almost as if the server is ignoring the client. This condition can only be remedied by rebooting the client computer, shutting down the AFS client software doesn't help. Neither does restarting the fs, volserver or entire AFS service on the server.
I've been able to find a few error messages, but this one (found through fstrace) was particularly puzzling as I'm not certain what it means:
fstrace lslog cmfx Logs for set 'cmfx': Error in enumerating set cmfx (errno = 2)
Additionally, the following message comes up for various hosts in the server's FileLog logfile. Clients that exhibit the issue show up in the log. There is a firewall between the server and the client which is probably part of the issue, however the clients typically work well enough. I would expect restarting the AFS client service alone would restore connectivity if the firewall lacking a connection was the problem. The network incidentally is not a reserved range, the IP addresses are fully routable. Client-initiated connections from any port are allowed.

Any ideas?
