NetBSD tyr 1.6_BETA1 NetBSD 1.6_BETA1 (GENERIC_DIAGNOSTIC) #0: Sat May 25 16:12:18 UTC 2002     autobuild@tgm.daemon.org:/autobuild/i386/OBJ/autobuild/Src-build-real/sys/arch/i386/compile/GENERIC_DIAGNOSTIC i386
>Description:
System uses amd to automount filesystems from NetAPP fileserver and from various SUN workstations. When daily cron job is run system panics in nfs_reclaim. The crash is repeatable. It also happens with the -current snapshot taken in mid-April. I have core dump for the DIAGNOSTICS kernel from the 5/25 daily build.

>How-To-Repeat:
It seems that the crash usually happens when /etc/daily runs "find \*.core" on nfs-mounted filesystems.
