gpg hangs in mlock, cannot be killed

[offby1]

I've noticed (by running "htop") a number of processes whose state is "D" -- uninterruptible sleep. This is unusual. A few of them are gpg.
gnupg version 1.4.9-3ubuntu1

I've also noticed that whenever I run gpg, it hangs, and I cannot kill it: not by typing Control C, nor Control Z; nor by switching to a different terminal, becoming root, and trying "kill -9" on the process' PID.

I can no longer do any encryption or decryption. This rather sucks :-|

I ran "strace -f -o yow gpg < some-file" and captured the output; the last lines are

10076 fstat64(3, {st_mode=S_IFREG|0644, st_size=256316, ...}) = 0
10076 mmap2(NULL, 256316, PROT_READ, MAP_PRIVATE, 3, 0) = 0xb7c9b000
10076 close(3) = 0
10076 mmap2(NULL, 32768, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7c93000
10076 getuid32() = 1000
10076 mlock(0xb7c93000, 32768

So it's hanging in "mlock".

Can you run gpg with "--verbose --debug-all --status-fd 1"? Maybe also add the output using "--list-packets".

I'm sorry, I can't reproduce the problem now.

Setting to "Incomplete" then for the moment. If you observe the problem again, please set this back to "New" and provide the requested information.

I've run into the same problem, also hanging in mlock.
I'm trying to upgrade to Karmic...

I ran

gpg --verbose --debug-all --status-fd 1 --list-packets --no-default-keyring --ignore-time-conflict --keyring /etc/apt/trusted.gpg --verify /tmp/tmpF3xNHa/karmic.tar.gz.gpg /tmp/tmpF3xNHa/karmic.tar.gz

which is the command that update-manager tries to run with debugging added.

No output is produced.
