I also get similar errors.  After them, Emacs usually becomes
unusable.

RMS advises to run Emacs under the debugger, to set a breakpoint in
memory_full, and to get a Lisp-level backtrace whenever the
breakpoint is hit, to find out why so much memory is needed.  Also
see the file etc/DEBUG for more information on debugging.  An Emacs
source tree is useful for this.

I've tried to do this, but got no real results.  The breakpoint
wasn't hit when I was looking, and when the memory was full, it was
too late to see anything interesting by attaching gdb to the Emacs
process.

Maybe you could try to find out something?

(I'm suspecting the Agent somehow -- I get the memory full thing
after doing `J s'.  But I have no idea what's happening.  Maybe I
b0rked the internal data structures and now Gnus is punishing me.)
