I apparently need some help with gdb to get useful output. After running "find-dbgsym-packages /usr/sbin/rpc.nfsd", I installed libc6-dbg and nfs-kernel-server-dbgsym. Then I stopped /etc/init.d/nfs-kernel-server just before the call to rpc.nfsd and ran gdb: # gdb /usr/sbin/rpc.nfsd GNU gdb (Debian 15.2-1) 15.2 ... Reading symbols from /usr/sbin/rpc.nfsd... Reading symbols from /usr/lib/debug/.build-id/4c/400a0c5314bb3884d7adbde7889a7bbc3a0eaa.debug... (gdb) run Starting program: /usr/sbin/rpc.nfsd [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". Program terminated with signal SIGSEGV, Segmentation fault. The program no longer exists. (gdb) bt No stack. Suggestions? Also, after rpc.nfsd fails, running it again (or, e.g., exportfs -r) hangs and can't be killed. The same failure occurs on another similarly-configured system. Thanks.. Bill
