I'm running an NFS server (5.4) and a client (6) that uses amd to mount the NFS shares from the server. I've been doing this for quite a while without any problems (before upgrading the client to 6). However, after the upgrade high file system load causes amd to hang often--I get a "pid123@blahblahblah not responding" message and amd is unresponsive for a minute or two. Mounting the same NFS shares *without* amd works just fine with the same usage pattern, so the problem appears to be with amd itself and is specific to FreeBSD 6. The client is using the BSD scheduler and has all debug.mpsafe* sysctls set to 1 (the problem still occurs when these sysctls are set to 0). Has anyone had similar problems? Thanks, Geoff
