Where bar2 is a volume not a local directory. what do you mean by crash? this has never been clear to me. does the openafs client box (the one running the cp -rpv) lockup? >>"Crash on nome " means Linux Operating system crash on "nome". I.e. "lockup". No response to keyboard, mouse or ssh. Sometimes ping 10.1.1.193 produces a reply, sometimes not. >>"Crash on denali" means Windows server does not respond (this not an issue with 1.3.87, just a comment that whatever caused it in 1.3.84 has been corrected). does it simply stop copying? >>Yes. And there are no rx packets from hiawatha, hiawatha is unaffected. if it locks up are there messages on the console that say something about an "oops"? >>No messages on xterm or in /var/log/messages. what happens when you copy the generated directory tree from one local volume to another local volume (both source and destination volumes are located on you local afs fileserver running 1.3.87 on your local network).
