The NFS server code is compiled into the kernel: options NFSCLIENT options NFSSERVER 2. The following NFS entries are in /etc/rc.conf nfs_client_enable="YES" nfs_server_enable="NO" 3. I upgraded to: FreeBSD 5.3-BETA7 #3: Sun Oct 17 18:51:58 CST 2004 and the panic hasn't happened since. Something else to note is that IPv6 was not compiled into the kernel. - aW 0n Sun, Oct 17, 2004 at 10:19:34AM -0400, Robert Watson wrote: On Fri, 15 Oct 2004, Wilkinson, Alex wrote: > Hi all, > > I currently get a panic with "nfs_server_enable=YES" in /etc/rc.conf. > > OS: FreeBSD 5.3-BETA4 #2: Tue Sep 14 13:55:30 UTC 2004 > > Backtrace > --------- > > panic: _mtx_lock_sleep: recursed on non-recursive mutex nfsd_mtx @ /usr /src/sys/nfsserver/nfs_serv.c:1947 Is the NFS server code compiled into your kernel, or is it getting loaded as a module? Do you have any other NFS-related entries in /etc/rc.conf? Could you show the output of "show locks" and "show witness" with witness compiled into the kernel? Thanks!
