Hi All, Got the attached panic whilst rsyncing to the box. The box has multiple snapshots on one filesystem (rolling 14day backup). kernel.debug,vmcore, dmesg, info.2 available from: http://www.clearchain.com/people/benjsc/download/freebsd-panic-20040210-5.2.1-p2.tar.gz (38Mb) Just after the reboot got the following lo reversal: acquiring duplicate lock of same type: "vnode interlock" 1st vnode interlock _at_ ufs/ffs/ffs_snapshot.c:1794 2nd vnode interlock _at_ ufs/ffs/ffs_snapshot.c:1796 Stack backtrace: lock order reversal 1st 0xc0954c40 UMA lock (UMA lock) _at_ vm/uma_core.c:1200 2nd 0xc1031100 system map (system map) _at_ vm/vm_map.c:2210 Stack backtrace: FreeBSD 5.2-RELEASE-p2 #2: Tue Feb 10 15:14:06 CST 2004 benjsc_at_rsync.levels.unisa.edu.au:/usr/src/sys/i386/compile/GENERIC GNU gdb 5.2.1 (FreeBSD) Copyright 2002 Free Software Foundation, Inc.
