I have configured Gnus to check news automatically every some minutes.
It works fine when I'm staying in one place, like company. While, when
after work, I go home by putting my notebook to sleep. Back home, when
I wake up the system, Gnus usually gets stuck, for like ten or more
minutes ? I can't do anything with emacs during that period. I often
have to kill and restart emacs at this time. What is the problem here ?
Any way to fix it ?

I captured some samples when that happens with ActivityMonitor. Looks
like it is blocked due to the __semwait_signal. The following is last
part in the sample. (The full sample is attached.)
Anybody has more ideas of what is happening here?

It seems that the network socket or IMAP exchange may be stuck. I need
to hear from you and Barutan about the second slave Gnus while the first
one is stuck.

Same as with William: can you do a URL retrieve in a second Emacs to
gmail.com so we know if it's a stateful problem in Emacs? If that
works, start a slave Gnus in the second Emacs and see if that works
while the first one is stuck.

I'm sure the problem is outside Emacs. When the stuck happens, I
sometimes dive into firefox for some time(waiting for emacs to become
responsible), but i never notice problem there.

Mac OS X 10.5.2.

Well, over here, gnus refuses to connect with gmail.com after a while.
I know their machines are working because i can connect to them from a
web browser, or with a new gnus. It's not my OS, and it's not
gmail.com, it's...

You need to use telnet and ping during the "stuck" period. Also try a
web browser during that time. That way you'll know if your OS or Emacs
are the problem, and what kinds of connections are working.
Please tell us what OS you're running, at least.

Since emacs gets stuck at this point, I'm unable to do this test during
that time. For after that stuck, I'll explain below.

After the stuck period, I checked Gnus group buffer, finding it failed
to connect to some newsgroup servers, for example, Gnus "Cannot open
server" for the following:
,----
| zen:~$ telnet aioe.cjb.net 119
| Trying 194.177.96.26...
| Connected to aioe.cjb.net.
| Escape character is '^]'.
| 500 Too long connection
|
| Connection closed by foreign host.
`----
Besides that, the gmane newsgroup server is still connected.
I don't understand why that long stuck period, what kind of TIMEOUT is
that...

Can Emacs open a network connection outside Gnus?
For example try (url-insert-file-contents "http://google.com") in a
temporary buffer. That won't use any Gnus facilities.
Then try the same for your own mail server, if there's a web server
running on or near it. If you can't get through, try command-line
telnet to port N (where N is your IMAP, POP, whatever port) and ping.
If those don't work either, the problem is outside of Emacs.
