This is easily reproducible when sending a lot of big files (+50-600MB) to low bandwidth NFS Servers (WLAN,DSL, etc).
Another thing is that while I was Sending files to the NFS Server, I tried to copy files from a Samba server and got the error message "File Descriptor error" or something like that. Syslog is also showing this: Oct 5 12:12:09 host kernel: [14040.451065] Call Trace: Oct 5 12:12:09 host kernel: [14040.451090] [<ffffffffa0f97440>] ? nfs_wait_bit_uninterruptible+0x0/0x20 [nfs] Oct 5 12:12:09 host kernel: [14040.451100] [<ffffffff81541557>] io_schedule+0x47/0x70 Oct 5 12:12:09 host kernel: [14040.451124] [<ffffffffa0f9744e>] nfs_wait_bit_uninterruptible+0xe/0x20 [nfs] Oct 5 12:12:09 host kernel: [14040.451133] [<ffffffff81541dbf>] __wait_on_bit+0x5f/0x90 Oct 5 12:12:09 host kernel: [14040.451159] [<ffffffffa0f9be80>] ? nfs_writepages_callback+0x0/0x40 [nfs] Oct 5 12:12:09 host kernel: [14040.451184] [<ffffffffa0f97440>] ? nfs_wait_bit_uninterruptible+0x0/0x20 [nfs] Oct 5 12:12:09 host kernel: [14040.451194] [<ffffffff81541e68>] out_of_line_wait_on_bit+0x78/0x90 Oct 5 12:12:09 host kernel: [14040.451203] [<ffffffff810845c0>] ? wake_bit_function+0x0/0x40 Oct 5 12:12:09 host kernel: [14040.451228] [<ffffffffa0f9742f>] nfs_wait_on_request+0x2f/0x40 [nfs] Oct 5 12:12:09 host kernel: [14040.451254] [<ffffffffa0f9b86f>] nfs_wait_on_requests_locked+0x7f/0xd0 [nfs] Oct 5 12:12:09 host kernel: [14040.451281] [<ffffffffa0f9ccae>] nfs_sync_mapping_wait+0x9e/0x1a0 [nfs] Oct 5 12:12:09 host kernel: [14040.451308] [<ffffffffa0f9d071>] nfs_write_mapping+0x71/0xb0 [nfs] Oct 5 12:12:09 host kernel: [14040.451335] [<ffffffffa0f9d0e7>] nfs_wb_all+0x17/0x20 [nfs] Oct 5 12:12:09 host kernel: [14040.451356] [<ffffffffa0f8bfba>] nfs_do_fsync+0x2a/0x60 [nfs] Oct 5 12:12:09 host kernel: [14040.451378] [<ffffffffa0f8c205>] nfs_file_flush+0x75/0xa0 [nfs] Oct 5 12:12:09 host kernel: [14040.451386] [<ffffffff81140bac>] filp_close+0x3c/0x90 Oct 5 12:12:09 host kernel: [14040.451394] [<ffffffff81140cb7>] sys_close+0xb7/0x120 Oct 5 12:12:09 host kernel: [14040.451401] [<ffffffff811498a6>] setup_new_exec+0x216/0x2e0 Oct 5 12:12:09 host kernel: [14040.451410] [<ffffffff8118d5c3>] load_elf_binary+0x3d3/0xea0 Oct 5 12:12:09 host kernel: [14040.451419] [<ffffffff811159a9>] ? get_user_pages+0x49/0x50 Oct 5 12:12:09 host kernel: [14040.451427] [<ffffffff8114a44b>] search_binary_handler+0x10b/0x330 Oct 5 12:12:09 host kernel: [14040.451435] [<ffffffff8114a9e1>] do_execve+0x231/0x2f0 Oct 5 12:12:09 host kernel: [14040.451443] [<ffffffff812bd46a>] ? strncpy_from_user+0x4a/0x90 Oct 5 12:12:09 host kernel: [14040.451452] [<ffffffff810105ba>] sys_execve+0x4a/0x80 -- 10.04 Lucid GUI Freeze when sending files over NFS https://bugs.launchpad.net/bugs/651333 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
