smbclient 3.2.4-3
kernel 2.6.27-ARCH smbnetfs 0.3.11a-1 fuse 2.7.4-1 When I use amarok to scan music folders mounted with smbnetfs (shared from a Linux box with samba), I find that after the collection scan gets to about 1 or 2% the files will disappear. Any attempt to access the mount from the command line gives a "transport endpoint not connected" error. I recompiled with symbols and used gdb to get the following backtrace: #0 0xb8065424 in __kernel_vsyscall () #1 0xb7b69720 in raise () from /lib/libc.so.6 #2 0xb7b6b058 in abort () from /lib/libc.so.6 #3 0xb7b365ad in talloc_abort_double_free () from /usr/lib/libtalloc.so.1 #4 0xb7b386a1 in _talloc_array () from /usr/lib/libtalloc.so.1 #5 0xb7d20ccd in next_token_internal_talloc () from /usr/lib/libsmbclient.so.0 #6 0xb7d20da9 in next_token_talloc () from /usr/lib/libsmbclient.so.0 #7 0xb7d8b3ca in internal_resolve_name () from /usr/lib/libsmbclient.so.0 #8 0xb7d8bb0e in resolve_name_list () from /usr/lib/libsmbclient.so.0 #9 0xb7d4b103 in cli_connect () from /usr/lib/libsmbclient.so.0 #10 0xb7cde346 in SMBC_server () from /usr/lib/libsmbclient.so.0 #11 0xb7cdf32f in SMBC_stat_ctx () from /usr/lib/libsmbclient.so.0 #12 0x08053e6f in samba_getattr () #13 0xb7cac352 in fuse_fs_getattr () from /lib/libfuse.so.2 #14 0xb7cad15a in lookup_path () from /lib/libfuse.so.2 #15 0xb7cafffb in fuse_lib_lookup () from /lib/libfuse.so.2 #16 0xb7cb5b41 in do_lookup () from /lib/libfuse.so.2 #17 0xb7cb61a1 in fuse_ll_process () from /lib/libfuse.so.2 #18 0xb7cb7b76 in fuse_session_process () from /lib/libfuse.so.2 #19 0xb7cb3bf9 in fuse_do_work () from /lib/libfuse.so.2 #20 0xb7c87145 in start_thread () from /lib/libpthread.so.0 #21 0xb7c0c63e in clone () from /lib/libc.so.6 (gdb) This is very repeatable for me, so if I can give any more info or do any other tests, please let me know. |
This task depends upon
Moreover, I wanted to test if anything else would cause breakage other than Amarok, so I ran a couple of "grep -R foo *" in a parallel. It took a while longer, but it did break.
