Subject: kernel BUG at page_alloc.c:84!
Date: Wed, 29 Nov 2000 21:47:32 -0600 [thread overview]
Message-ID: <20001129214732.A2513@intolerance.digitalpassage.com> (raw)
I've been noticing some nasty problems with 2.4.0-test11-pre7, constantly
getting out of memory problems running megahal ( a conversation generator),
I think it has a memory leak.. nothing else seems to cause this.
