Subject: Gnus in stuck state with gnus-demon
Date: Fri, 16 Nov 2012 14:15:54 -0500

For my gnus setup, I have various nntp servers, nnimap, and nnrss servers. 

I have set the following for fetching mail and news automatically: 
(gnus-demon-add-handler 'gnus-demon-scan-news 30 1)
(gnus-demon-add-handler 'gnus-demon-scan-mail 31 t)
(gnus-demon-init)

Quite often, I see gnus stuck, the last message being about nndraft. I
can break out of it by pressing ctrl-g. It doesn't seem to be just gnus
getting msgs, I have been patient and waited for a while with no
movement.

After breaking, in *Messages* I see the following:

......
nnimap read 82k from imap.gmail.com (initial sync of 3 groups; please wait) [2 times]
Reading active file from archive via nnfolder...done
Reading active file via nndraft...done

Set `debug-on-quit' and post the backtrace you get when you `C-g' when
it hangs.

Sorry, I had forgotten about posting this info. Here is an example of what I see when I break, this was showing stuck when starting up gnus normally.

So Gnus is hanging waiting for data from the NNTP server.  I could see
that happening if you're issuing interactive commands and the daemon
triggering at the same time.  There's code in there that's supposed to
make that impossible, but perhaps that code is buggy.

Have you been able to determine what triggers this bug?

More data was requested a year ago, but none were giving, so I'm closing
this bug report.  Please reopen if further progress is made.

I mean:

More information was requested three months ago, but none were given, so
I'm closing this bug report.  Please reopen if further progress is made.
