Hi !
Linux 2.2.1 oopses after putting (silly) high values into /proc/sys/net/core/[rw]mem_{default,max}.
I've tried this and then a while(1) write(sock, msg, 2<<21);
while the other end was not reading. It write returned after queuing the full buffer (2MB(!)) and was blocked the second call.
From this point the machine starts oopsing but without running out of memory. Nearly anything else fails by segfaulting after that and a graceful shutdown was not possible.
