Sometimes Gnus need a very long time to check e-mail

Sometimes Gnus need a very long time to check e-mail

[Cecil Westerhof]

I have Gnus checking every half hour (when Emacs is idle) for new
e-mail/articles. Most of the time it is done in about 20 seconds. But
sometimes it takes more as half an hour. (And sometimes even a lot more
as this.) Can that be a problem with Gnus, or has this to be a
network/internet problem?

Also when I use C-g because I want to do something in Emacs, I have to
leave Gnus and start it again to get connection with my e-mail again,
because after the C-g Gnus can not connect to the server anymore.

Hi Cecil,

Check if there is an issue with for example an openssl instance that is
disconnected on the other side? In my case,  hitting g in the gnus
buffer will start

openssl s_client -connect mail.server port -no_ssl2 -ign_eof

and I've noticed that at times an already running openssl connection
will have been severed by one or the other machine, causing gnus to
wait..

Hm. I have a feeling that is your set-up, not Gnus. I don't recognise
that.

In principal hat could be it, but how do I find that the other site
disconnected?

Since yesterday 11:40 I had one time that it took long:
    2010-04-07 02:46:59: Start with getting new news
               03:17:27: Done with getting new news (0:30:28)

Normally mail/news is fetched every 30 minutes. But only when Emacs is
idle. I have the feeling that in the past it happened more often, but I
am not sure about that.

Try a g and immediately C-g so that Gnus does not finish but you
terminate the fetching.
