[Bug 431975] Re: downloading a torrent to an encrypted home partition hangs and uses 100% CPU

 

I have this in top:
 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND          
3663 user       20   0     0    0    0 Z   96  0.0 452:08.31 transmission <defunct>

killing with sudo kill -9 3663 with no avail
the parent of 3663 is init with the processid 1

the stack for 3663 is 
[<c0147ea6>] do_exit+0x1c6/0x2e0
[<c0147ffa>] do_group_exit+0x3a/0xb0
[<c015403f>] get_signal_to_deliver+0x18f/0x300

[<c010318d>] do_notify_resume+0x4d/0x60
[<c0103448>] work_notifysig+0x13/0x1b
[<ffffffff>] 0xffffffff

in dmesg a crazy amount of the same error messages
[26030.752479] Valid eCryptfs headers not found in file header region or xattr region
[26030.752483] Either the lower file is not in a valid eCryptfs format, or the key could not be retrieved. Plaintext passthrough mode is not enabled; returning -EIO

at the very start:

Bug description:
Karmic with all updates. Home is encrypted with ecryptfs.
I have tried downloading several torrents with thansmission and rtorrent. When downloading to the encrypted home, both programs hang, use 100% CPU and I can't kill them. Downloading to /tmp, which is not encrypted works.
