(another posting to 4bsd.bugs included a patch which doesn't apply to 386BSD). -AM From: julian@tfs.com (Julian Elischer) Subject: IMPORTANT PATCH! Message-ID: <1992Nov3.071934.25466@tfs.com> Organization: Trw Financial Systems Date: Tue, 3 Nov 1992 07:19:34 GMT Lines: 49 The following patch fixes a randomly initialised variable in the icmp and raw socket code that can cause 'ping' and 'traceroute' to never fully close their socket's internal structures leading to a geometrically increasing number of lost mbufs until the system runs out of appropriate virtual space, at which time the system panics with a 'kmem_alloc: map too small' and halts. EVERY time you run ping and traceroute you make the problem worse The 'rights' entry should not be there. julian +----------------------------------+ ______ _ __ | __--_|\ Julian Elischer | \ U \/ / On assignment | / \ julian@tfs.com +------>x USA \ in a very strange | ( OZ ) 2118 Milvia st.
